I'm pretty new to Zimbra and wonder how Zimbra can be extended by propriatary functionality:
I read about the so called Zimlets as a way to add functionality to Zimbra. As far as I was able to find out, those Zimlets appear in a special area on the right side in a separate box. What I need to do, is to add functionality to Zimbra, that goes far beyound a new Zimlet in a box on the left side of the user interface: I want to add much more functionality. E.g. I want to replace the login mechanism with a completely differnet login funcionality. Also I want to add new DIV's on the User Interface, which contain complete different functionality.
So, if I complete want to rearrange the GUI, that is predetermined by Zimbra, how would I do this (or is this possible anyhow?). Usually, one would expect to have something like a graphical editor, where one can rearrange the DIV's and contents of the user GUI, afterwards you would clik on somethin glike a "Generate"-Button and then the complete AJAX-Code would be build. Is there somethink similar in Zimbra? Or will I have to edit teh AJAX-Code (=js-Files) of the Zimbra sources (if so, it seems to me, that adding extensions means a huge effort, if not to speak of an almost impossible mission)?
Thank you for your reply in advance!
