I'd like to see various tweaks to the email app that I haven't seen covered elsewhere:

  • add a 2nd set of arrows (like the ones on the sides of the subject section) at the foot of the message--it's maddening thinking "yes, I want to keep this message" and then having to scroll back up to move to the next one!

  • option to change/expand delete functionality--enable "del+next" (and maybe "del+prev"); for space reasons, that should probably be user-selectable... if you use Fastmail, they have these options on their site (delete has a button and the other two have links on the right side--one of each above and below the message)

  • support for email aliases!
