Custom zimlet for Zimbra 8 - repost

Greetings, I'm looking for someone experienced with Zimlet development for Zimbra. I need a Zimlet that can create "tabs" on the top menu bar and also a custom box on the left bar of Zimbra's webmail client. The tabs on the top menu bar, should be links for embedding websites on webmail The box on the left side, shoud also contain links for embedding websites. I also need This zimlet to have an admin interface on ZimbraAdmin. At the admin interface we need the following options: * Name * Description * URL * Ordering on top bar (0 for not showing, any other number for ordering) * Ordering on left bar (0 for not showing, any other number for ordering) (Doesn't need to be exactly like this, but those are the features that I need) Zimbra Version: ZCS 8.x Thanks!
