[feature] link upload and/or additional buttons with custom functions

[evesdropper]

Wondering if it'd be possible to have a button that uploads to an image server (e.g. I currently have a script that uploads to imgbb) and copies the link onto clipboard like how lightshot (which I used on Windows in the past) worked.

This might force people to use one specific image server so I was thinking if not then maybe it could be possible to put additional buttons/keymaps that could map to custom functions such as uploading to an image server.

I am not against it. But I am not sure, if we have the time to develop and maintain those features?
