One little UI quirk I just noticed you may want to fix: on the Edit menu, both "Paste" and "Preferences" have the "P" as their selection key, which means typing Alt-E P just switches between the two without selecting either (if there's stuff to paste). This showed up in Gnome terminal recently too (see https://bugs.launchpad.net/ubuntu/+source/gnome-terminal/+bug/290777 ).
All the apps I just checked make "P" execute "Paste", but the key for "Preferences" isn't so standardized. Just among Gnome apps, gedit uses "E" while Rhythmbox uses "N". Mozila Firefox/Thunderbird both use "N" as well.
