CFay,

I installed the
Sense 2.1 Email Tab Add-on V2 ported from Sense 2.5 cab to get the full page mail image offered with sense 2.5 (it did not work). But it's a cool idea that's starting to appear in other Sense 2.1 ROMs... maybe you can pull this off as a cab or feature of 1.5?
I subsequently installed SilenceROM 2.5 Mail Tab.cab which doesn't break Sense, but the email page doesn't fully fill the screen. Food for thought.
