The good news is a few lines of shell scripting, grim, slurp and satty can be combined to create a decent alternative.

Hit a hotkey, capture a region, get presented with a way to annotate it and easily copy it to your clipboard or write it to disk. I use it on a multi-monitor system and it works no problem with Wayland.

Here's an example from my dotfiles: https://github.com/nickjj/dotfiles/blob/master/.local/bin/do...

It supports capturing a region, a specific window or the focused monitor.

Flameshot with sway has been a nightmare for me. I have tried a couple of times but i have never gotten it to work. I have settled with grimshot. The biggest missed feature is the number annotator. It was so easy with flameshot to annotate a screenshot with 1-9 and then refer to each number in a document. I really miss flameshot:(

		The solution I posted includes an incrementing number annotator btw. Satty has a lot of great features. You can even capture the whole screen so that you can crop it after you've done your annotation which is similar to how Flameshot works.
