And here is a new possible function:
Filter plugins based on calibre version.
I use 0.8 so the goodreads-plugins prior to 0.8 can not be installed.
Is it possible to filter plugins that are not compatible with the current version?
(So for 0.8 remove prior versions and for 0.7.x remove later versions)
Would be a nice option. Or maybe you could show plugins that need a more recent version of calibre but disable them (gray) so you can see there are more plugins if you upgrade to a new version of calibre.
