I'm trying to get a better understanding of zimlets and how they're deployed in Zimbra; I disabled all the zimlets in the distribution using the command line (to have a clean environment for zimlet creation). I am now trying to reactivate all zimlets again... but some refuse to appear. The wikipedia zimlet panel item doesnt' reappear, even when re-enabled (according to listZimlets). Also, the "search" zimlet panel item reappears, but doesnt do anything when clicked.
Also, how does the <tooltip> tag work? Mousing over on top of panel items doesn't yield the expected tooltip even with the tags in place.
