The UI just needs to be streamlined into one, simple, clean UI. The side Menu is even too much; it works I will give it that--but everything is just a chore. Inventory, Actions and Traits, Party, Linkshell, and Journal should all be tabs in the quick menu on the bottom. Graphic settings should be available within the game and the side menu should be mainly for console controls. There should be multiple ability bars instead of one with arrows to go to different lists, sometimes it's just nice to have all your abilities readily available to click. The Icon size on the Action Bar should be an option in the menu, and overall the action bars should take up as much space as they do. There should also be an option to have the action bar viewable at all times, as well as keybindings for all the different menus.

Inventory should be completely redone to where instead of having a list you have a chart with all your items viewable inside, and can easily drag and drop the icons. There should also be an AUTO SORT option for the inventory to group items into like groups so that organization isn't an issue. Items being worn by the player should be removed from the inventory, because they are actively being worn--it's impossible for an item to take up two spaces at any given time, and plus it's just annoying and confusing. Maybe splitting the inventory up into categories itself, "All, Armor, Materials, Usable Items, Weapons, Accessories, Misc" so that the player can easily peruse the inventory would also help.

The player skills menu should also have a way to easily flip through classes and skills, tabs are always a better option for categories than a scroll down menu, so maybe have the classes in a tab on top or to the side. This way a player can easily view the skills they want and organize everything much quicker and more efficiently. Also having the Action Bar for each class be saved would be nice so you don't have to reset it EVERY time you change classes.

Everything in the UI needs to be more easily accessible and quicker to peruse through, I'm a patient person but some things in the menu are just too much of a bother. Selling things is almost more of a hassle than I care to partake in, so often I just let my inventory stay full because it takes about 10 minutes to clear it out.

Also the Bazaar for retainers needs to be greatly expanded, or the can just give us an AH where we can sell a greater quantity of items.
