Works Rated 4 out of 5 stars

This seems to be the only living and free add-on out there that can take screenshots directly into the clipboard, thus I like it.

There's a bug though: it fails to give the file extension when saving the screenshot as a file.
It just gives "." instead of ".png" or ".jpg".

I'd like a toolbar button, too.

Pity the repo on github is outdated.
