I was wondering is there support for displaying the UI in a Right To Left format ?

I'm interested in translating Zimbra to Hebrew and I admit I haven't looked into the source code.

So basically my question is this, does Zimbra have a UI mechanism that allows the UI to be displayed RTL.
If so great I will look into the translation task if not, is it on the future features list or shall I give up on this idea ?

Thank you in advance and sincerely yours,
