My suggestion is simple. Here it is.
-1: Add subject title to the notice of receiving a new mail. Example: "New mail received from Auction House: Outbid Notice." If there is no subject, then it should read "No Subject."
-2: Add a shortcut key binding to the Spiral Uplink (mail inbox).
That's it!

An option to turn off the UI would also be great.
