A while ago our amazing sysadmins upgraded our bugzilla installation from something aging to something more modern. Hurrah! We are not a billion years behind in another software! Hurrah!
Unfortunately this meant we lost some of our ¿custom? code that allowed to show the Votes column in searches like this (click on the change columns link at the end).
One can still see the votes in a particular bug, but for things like wishes it was very useful to be able of sorting by votes.
So it would be extremely cool if you can try to implement this, be warned, it's probably not going to be easy to implement and moreover bugzilla is in perl, but i'll owe you a few beers if you make it :-)
If you want to help do not hesitate to contact me on email@example.com and I'll forward you to the appropriate people, or even better just join the #kde-sysadmin channel in irc.freenode.net and present yourself as volunteer to do this job.
