I just got updated via Google this morning, very nice clean new look and feel! I've not been on the forums for a while, so I hadn't seen the latest stuff, nice work!
One quick issue: the new 'drag-to-select-multiple-messages' feature doesn't seem to work as I'd expect: if I try to select (say) the first four messages on the screen, when I release my finger on the fourth message it selects everything in the Smart Folder rather just the four messages I was trying to get.
(Oh, and for the record, I've disabled the little round floaty new-message icon - it may be Google's fancy new toy, but for me it's no substitute for an on-screen refresh button amongst other things)
Great work anyway, excellent app.
