Some time ago it was added to the CodeReview extension the feature of showing a tooltip to the r999 links containing a summary of the corresponding revision. This is cool!
I think it would be very useful to have this kind of tooltips also for Phabricator links on Gerrit, displaying the summary of the bug (to avoid opening a link just to read its title). E.g. in the bugs listed at
