With the sunsetting of the standalone Manjaro Screenshot app in favor of the Wayland compatible Screenshot Shell app, the copy-to-clipboard functionality got lost afaik.
Happens to be my most common use of screenshots though. I almost never have a need to permanently save them and clipboards make workflow so much easier.
Thoughts on why this got lost, and how to bring it back?
I personally use Flameshot on Plasma Wayland and it works without an issue. So I recommend it. It has an option to save ore to copy the screenshot, IIRC.
It’s in the extra repository:
$ pamac search flameshot
[...]
flameshot 13.3.0-2 [Installed] extra
Powerful yet simple to use screenshot software
