Icon for "mark all read" at bottom of smart inbox

[jeffw_00]

Hi - when I open Aquamail (to smart inbox), I often want to Mark all read (it's an ex-blackberry user thing).  I know I can do it in the menu, but since there are only 3 icons at the bottom of your screen - why not add a 4th and make me more efficient.

Loving it otherwise

does anyone think this is a really good idea?  there's room for the icon - and should be an easy code change 8-}
