It is possible and simple, you must edit the xml definition file of the zimlet, and change this line :
I am using ZCS 5.0.8 and I want to change the label/name of the zimlet that is displayed in the left zimlet panel. Is this possible?
<zimletPanelItem label="LABEL" icon="ICON">
Just change the label in whatever you want.
It is possible to add a panel inside the zimlet's panel with a zimlet but it's surely not an easy thing to do.
I am trying to integrate Zimbra with an InstantMessaging application, and I want to display the current status of the user in the left zimlet panel, along with some custom status text (like "stepped out", or "be right back") so it would be nice to put a custom panel in the left panel, instead of just a simple text.
