Chinook here. The previous version was OK - this one doesn't do at all. Settings menu doesn't come out, when trying to clip selected text from browser, get "error clipping", and clip files aren't shown.
Downgraded to 0.11 - OK again.

Might be I had to uninstall/purge 0.11 before installing 0.12?
EDIT: nope, after purging 0.11 and /home/user/.quickclip and reinstalling 0.12 no menu comes out when clicking its icon. Definitely, 0.12 is not chinook compatible.
