I use Sharex on Windows and I don't think there's any better tool, so I searched for "run sharex on linux" and there is indeed a guide - https://github.com/ShareX/ShareX/issues/6531 - maybe you can get it to work?

I believe it can do all of the things you want. Certainly area capture, remembered area capture, fullscreen capture, all bound to different hotkeys. Mine saves with the name = the timestamp but you can probably config it to be an incrementing index. It's incredibly full-featured.

I also have hotkeys for "capture current pixel's hex code" and "measure bounded box in pixels." When you take a capture you can also annotate it including showing labeled steps. After capture you can do one or more of: save locally (to one or more places), upload (to one or more hosts), copy to clipboard, etc. That includes pastebin if you have text saved to your clipboard so I use this for that also.

I can't recommend ShareX enough, it is the most well thought out, intuitive and comprehensive tool for handling screenshots. I really miss it on Linux, I'll try that guide.

Thanks, looks featureful. But I really need it very stable so running it in wine is a dealbreaker, since I already have a wine setup I have to fumble with a lot to get different windows executables to behave in certain ways.
