What's weird to me is that this was being discussed last year (
Home Tab: Project, Features, & Layouts), but no RFE's or bugs were submitted? Anyway, I've voted on Bug 40254.
EDIT: Didn't notice (
Bug 24551 – Home Tab GA - Requested Layouts & Features) listed in that thread. I am
very interested in this, as are many other people I'm sure. Because so many of the related bugs are internal to Zimbra staff, it's hard to tell how far along this is.
