Aqua Mail looks beautiful on my Nexus 7 in landscape mode. On my Galaxy S2, in portrait mode, however, the mail list view (already in "compact mode") looks rather cramped and cluttered.
It would be nice if there was an option to hide either the checkmarks, or the stars, or both, from the mail list view and only view them when needed.
In fact, while not of utmost importance, it might be nice to have an option to hide the size of a message, making the UI even less cluttered.
