Windows has this builtin capability to make freeform screenshots via Windows-Shift-S. The image illustrates what I mean by freeform: Draw a polygon on screen and only capture that.
As far as I know, nothing on Linux provides this capability. Shutter is generally considered the most advanced screenshot app but it can only do “rectangular” areas.
Maybe I missed some app though?
Right. I’m using this for war gaming under some time pressure. So I’m looking to optimize. A detour to Gimp means at least double the time.
