Good thing you clarified or I would have thought you were talking about the icon associated with an application entry.

I never thought of doing that, probably at least partially because I like to see the Personal Menu icon in people's screenshots! I don't think there is any technical limitation that would prevent implementation, but it would definitely require the user to either unload/reload PM or reboot their tablet.

I'll take a look at this when I have some time for Personal Menu again. Thanks.
