Flameshot was great, but for me, no window select (on Win) and no plan to implement is a deal breaker, thoughi understandthe reasons.
Also breaks when moving between docks - has to be restarted, and pinned images go under the screen, if pinned at the bottom (they always shift down).
While I like the UI, it makes it awkward to quickly find the icon needed on small crops, since they keep shifting around.
