Screenshot tool

Nobody has claimed this yet.

### Expected

Something as good as [ShareX](https://getsharex.com/) ([GitHub repo](https://github.com/ShareX/ShareX)) that I used on Windows

### Potential solutions

Screenshot tool

- Built-in: `xfce4-screenshooter` (just search for `Screenshot` in the apps)
- https://flameshot.org/
- `pamac install flameshot`
- No gif capture
- Works fine for basic screenshotting
- `pamac install peek` :heavy_check_mark:
- This works pretty well for gifs
- Only problem is that it's [deprecated (as of 2023-01-14)](https://github.com/phw/peek/issues/1191)
- `pamac install kooha` :x:
- I couldn't get this one to work and seems like [they don't support non-GNOME desktop environments](https://github.com/SeaDve/Kooha/issues/10).

- TODO: Find something better

Start by reviewing the listed alternatives—xfce4-screenshooter, Flameshot, Peek, and Kooha—and the linked ShareX reference. Compare screenshot and GIF-capture coverage, then update the Screenshot tool notes with a suitable recommendation, installation details, and known limitations; remove the TODO when the recommendation is documented.
