Nifty app!

Just tried the AppImage version on Linux, simple to use, and works Ok on my end.

Suggest you add preferences dropdown to floating bar, and ability to highlight parts of an area for record, ability to set the default save location or change it at will. Also noted that though I closed the app via the customary way, and removed the AppImage, the apps ICON remained present in GNOME's notification area.

Will keep an eye on its progress since OBS (what I used) seems to have stopped receiving updates :)
