Here are some little things that I’m still hoping are implemented:
Keymaps Unique to Characters: I’ve got to remap almost every time I log from one toon to another. Some profs use just F1, some use F1 to F4. As such, I rebind F2-F4 on profs like Thief, Necro or Warrior and then have to rebind once again for Mesmer or Ele.
“Randomize” at Character Creation: In other games, this has always been a easy way to find cool appearance combos that we might not have found on our own.
TP preview: a redundant request, but Andy Dufresne got his library books from writing a letter a week. 
LFD: Andy would also like LFD
