Window Tools: Can I include a folder in a window set #627

Hi like the functionality of window sets, and now with the cool new folder views (kanban!) I would like to create a floating window that has just a folder open for viewing in Kanban mode. I've tried configuring the filename to be a folder, and unsurprisingly (maybe) it breaks the window set. So that when I try to open a window set I get a message that there are no window sets defined for this machine.

Describe the solution you'd like (the 'how')
I would like to be able to have a floating window by configuring a folder rather than a file.

Thanks for your work!
