Monorepo of independent Tampermonkey/Greasemonkey userscripts. Vanilla JavaScript, no build step.
A global userscript that automatically detects and focuses search input fields on any webpage, so you can start typing immediately without clicking.
Features:
- Cascading search field detection using semantic roles, input types, name attributes, placeholders, aria-labels, and common IDs/classes
- Dynamic detection via MutationObserver for search boxes that appear after page load (modals, SPAs, Ctrl+K dialogs)
- SPA-aware — re-triggers on
pushState/popstate/hashchangenavigation - Safety checks — never steals focus from inputs you're already typing in, respects pages that auto-focus their own search
- Floating indicator with settings popover — appears briefly when a field is focused, click to toggle per-site enable/disable
- Keyboard shortcuts:
Alt+Shift+Sto toggle on current site,Alt+Shift+Nto cycle through multiple search inputs - Per-site exclusion list stored in localStorage

A unified userscript for YouTube — "YouTube without the garbage." v1.0.0 is a scaffolding milestone: the shared duration parser is in place and the subscription-feed duration filter is registered as the first feature module, with DOM detection and UI landing in follow-up commits.
Features:
- Pure duration parser / formatter (HH:MM:SS ↔ seconds) — extractable, testable utility shared across features
- Feature-module architecture — each feature is route-scoped and re-runs on
yt-navigate-finishso it activates/deactivates as you move between YouTube pages - Duration Filter module (subscription feed) — scaffolded in v1.0.0; full DOM detection, filtering, and settings UI land in subsequent versions
- Per-feature logging prefixes (
[YourTube],[YourTube/Duration]) for easy console scanning - Shared versioned settings blob (
yourtube_settings_v1) keyed per-feature

A userscript for ChatGPT, Claude, and Gemini that widens the narrow chat column to fit the monitor you actually have.
Features:
- Per-site width, saved separately — a width that reads well on ChatGPT isn't the one that reads well on Gemini
- Slider from 50% to 100% of the window, with
Comfortable/Wide/Fullpresets, and a live readout of the width in pixels (≈ 1120 px of chat · 80% of this 1400 px window · site default 768 px) - Live preview — the page resizes as the slider moves, so the width you pick is the width you can see
- Optional "match the input box", so the composer can follow the thread or keep the site's own width
- Selector-light engine — walks up from a message (or the composer) and widens whatever the site capped along the way, so churn in generated class names costs at most one anchor
- Tables and code blocks follow the column too — where a site pinches its own table wrapper (Gemini clips wide tables mid-word), the wrapper is grown to match; a table that fits is left exactly as the site drew it
- Never narrower than the stock column, whatever the window size
Alt+Shift+Wtoggles widescreen; switching it off leaves no trace of the script on the page- Floating pill with an LED that reads on or off at a glance, and a two-step reset

- Bundle-level ratings: top-N average, depth score, and personal score (excluding owned games)
- Deal quality metric (unowned MSRP vs. bundle cost)
- Side evaluation panel with score histogram, top picks, and per-tier breakdowns

- One-click "Copy Summary" to clipboard
- Settings persist in
localStorage

A userscript for Fanatical order pages that bulk-reveals and bulk-redeems Steam keys.
Features:
- Floating control panel on order pages with Reveal All, Redeem All, and combined Reveal + Redeem buttons
- Sequential key reveal with delays to avoid API rate limits
- Redeems keys via existing "Redeem on Steam" buttons, with fallback to
steam://registerkey/URLs - Status display showing current progress and game names

A userscript for Amazon Luna claim pages that opens available Prime Gaming claim pages and redeems exposed keys with optional per-store filtering.
Features:
- Floating control panel on Luna claim pages with reveal/open and auto-claim controls
- Opens claim pages in background tabs with configurable pacing
- Auto-claim handoff via URL flag so newly opened claim tabs can continue the flow
- Store detection for Amazon Games, Epic Games, GOG, Legacy Games, and Microsoft Store — a claim for a store it can't identify is refused, never guessed
- GOG: follows the "Claim code" link to gog.com in the same tab, then clicks Continue and (after asking, or automatically) Redeem exactly once
- Each claim is checked for a success signal instead of assumed; unconfirmed claims are flagged in red
- Per-store enable/disable settings persisted in
localStorage - Update banner using the repo's metadata check pattern

A userscript for Odoo that converts HEIC/HEIF images to JPEG client-side before upload. Solves the browser HEIC rendering gap on Odoo SaaS where server-side conversion is blocked by sandbox restrictions.
Features:
- Automatically detects HEIC/HEIF files in file picker and drag-and-drop uploads
- Converts to JPEG client-side using heic2any before Odoo processes the upload
- Toast notification confirms conversion count
- Graceful fallback — if conversion fails, the original file is uploaded rather than silently lost

A userscript for YouTube Music that adds a single-click pill button to hand off the current track/playlist to the YouTube Music Desktop App via its ytmd:// custom protocol. Completes the YouTube → YouTube Music → YTMDesktop chain when paired with yt-music-redirect/.
Features:
- Single-click pill button anchored in the top-right of
/watchpages — no menus, no modes - Launches the current track in YTMDesktop and pauses the browser tab so the desktop app plays alone

ytmd://play/<VideoId>[/<PlaylistId>]protocol without navigating the tab - SPA-aware — mounts/unmounts on
yt-navigate-finishso the pill only appears when there's a track to hand off - Requires YouTube Music Desktop App installed (registers the
ytmd://protocol handler)

A userscript for YouTube Music that fills the empty space on /watch pages with a data-rich floating panel — the kind of info that's normally only on the YouTube page, surfaced directly in YTM.
Features:
- Floating, collapsible panel anchored in the top-right of
/watchpages (collapsed state persists inlocalStorage) - Overview section — title, author, view count, length, publish date, and category
- Auto-detected chapters — parses timestamp lines (

- Full description text, preserving line breaks
- Reads YTM's in-page

A userscript for Prime Video that removes titles you don't want from storefront rows, search results and your watchlist. Hidden titles are removed so the rest of the row closes up.
Features:
- Hide titles not included with Prime — rent, buy, and paid-channel titles. Cards carrying Prime Video's entitlement marker are hidden by a CSS rule the moment they render, with no wait for the script; others fall back to their labels. A title the script can't check stays visible.
- Hide titles you've watched — from each card's progress bar, with an adjustable "counts as watched at" threshold (default 90%)
- Hide low-rated titles — below an IMDb rating you choose (default 7.0). Ratings are read from the card when it shows one; otherwise from the title's detail page, fetched four at a time, newest-scrolled first, only for cards near the screen (and the next few along each row), and cached for 14 days. Titles with no rating stay unless you turn on "Hide titles with no IMDb rating".
- Hide rows with nothing left, so an all-paid row doesn't leave a bare heading
- A "⧩ Filter titles" button in the bottom-right corner shows how many titles are hidden (it pulses until you first open it); the panel explains the count (e.g. "Hiding 23 of 140 titles — 12 not included, 6 watched, 5 rated below 7.0")
Alt+Shift+Fpauses and resumes filtering so you can see everything- Every filter is off on a fresh install
- Label matching is English-only; the entitlement marker and progress bars work in any language

Scripts that are no longer functional or maintained. Kept in the repo for reference — not served via raw URLs.
A userscript for Bonjourr new tab pages that provides a quick interface for adding shortcuts with automatic page title fetching. Not functional — Firefox's extension security model blocks userscript injection into moz-extension:// pages. Kept in the repo in case browser APIs or Bonjourr change to make this viable. See REPORT.md for the full post-mortem.
A userscript for Odoo SaaS instances that restricted Google Places Autocomplete results to Canada with a location bias toward Southern Ontario. No longer maintained.
A userscript for lichess.org that stripped the homepage down to essentials for casual play. No longer maintained.
A userscript for llm-stats.com leaderboard pages that auto-paginated through all models and displayed them in a single table. No longer maintained.
