I'm using the Social Zimlet, and have two feature suggestions (or questions, if these are already implemented). The zimlet is whichever version is installed in Zimbra Desktop 2.0.1 on Ubuntu (from the source tarball as of 2-18-11).
My suggestions are these. First, I would like to be able to create columns for each of my twitter lists. Secondly, I would like to increase the number of updates shown for facebook.
On an unrelated (or slightly related) note, is the LinkedIN zimlet available for Zimbra Desktop as well as ZCS?
Have a great day
