I'll remind you that GDesk is a famous UIQ 3.x application that enables you to make your desktop system customizable and extendable. Icons can be placed on the desktop representing applications, page links and plug-ins; these can then be launched by tapping them. Plug-ins can be added at any time and as required; further plug-in functionality will be provided over time.
I'll provide screenshots later on ;)
NB : Don't fotget to sign it!
