Hey mods just throw these where ever you will, I'm not reading through 800 million pages of stuff to see if anyone is as brilliant as I am.

Inventory/Storage - Add a screen at login with access to the inventory of all characters as well as your storage vault so you don't have to keep logging in & out to move stuff around.
Quest Log - Add a tab that shows what quests you've done as well as an indicator that shows how many you've done out of how many are available in that particular area.
Controls - Add the ability to toggle “Ctrl” and “Alt” both in and out of towns...unless you want to pay for my next carpel tunnel surgery.
Armor Crafters - Add a preview window similar to the one for applying dyes so you can see what it actually looks like on your character before buying.
Tiered Key/Chest System. - Different levels of keys and chests based on price so you don't need to keep a bunch of different types of keys on you or buy and sell them for a loss of gold every time you play in a different area.
Party List - Add an energy bar and death penalty indicator. The energy bar could be a thin blue line underneath the life bar and add a small box at the end for DP. This should also apply to pets, NPC's, and possibly your target perhaps???
Hero/Pet experience level. - It'd be nice to see it somewhere as well as have the ability to feed them CC's.
Maps - Zoom in & out on the large map(more than 2 settings). Available on the small window map.....not really sure why. Seems it'd be more useful on the biggins.
Map Icons - Adding indicators to collector locations was a nice start. I'd like to see it for all NPC's you uncover in your travels both on the big and small map.
Mapping - Make the portions of the map you haven't uncovered yet more easy to differentiate for those of us who've burned out their retinas playing video games 10 hours a day.
