Comment 100 for bug 527458

I think the most compelling use case for tooltips (aside from the battery indicator) is the music player. I like to be able to quickly see what's playing, without having to click on anything. Granted, this isn't a problem for users of Docky, which can support such tooltips for Rhythmbox's dock icon, so maybe something along those lines would be the best way to deal with that issue. That doesn't help the battery indicator situation much, though.

Furthermore, KDE application indicators have tooltips, and I don't think they will be willing to change that, so supporting tooltips for GTK+ application indicators would help from a consistency standpoint.
