i use this at work, and its great. Only downside is, that the buttons are hard to identify and move depending on the size of the screenshot, so you always have to search for the function you need.
For the longest time I used gnome-screenshot via shortcuts that execute terminal commands. Nowadays, I use my dedicated print screen button (that probably just executes similar commands and uses gnome-screenshot on the background).
For Windows, I recommend ShareX. It feels more modern than Greenshot, has more features and is more customizable. And it's open-source: https://github.com/ShareX/ShareX
On Mac, with multiple displays, it seems to be broken. Sometimes it targets the wrong display, and mixes the resolutions. Have tried for a while because it seems perfect on Linux.
Same page has instructions for choosing which key-combo should bring up the GUI. I'm on Ubuntu and had to do special steps to make it work with the PrintScr key but it's so easy to use now!
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.
A great tool, wish they had a feature that would allow you to add plugins/add-ons such as OCR, GIF Maker etc. Similar to what FlowLauncher offers plugins wise. (FlowLauncher is a FOSS system wide search engine for windows).
Flow Launcher is way more powerful, customisable and has plugins support. Power toys run is pretty limited. With flow launcher you can direct search internet queries with your favourite search engine.
Anyone know a screenshot tool that can do this effect easily and directly? I tried out a lot of tools and I'm unable to find any. Currently I'm using either Inkscape or Illustrator to get this effect. This is really good effect to prepare documentations.
.NET works on non-Windows OSes too, at least enough to have a GUI. Avalonia is cross-platform for example. Not only across desktop but also mobile and web.
