This is by no means some list I have been putting together extensively for the past 3 years. Just a few items off the top of my head that I think would be a nice boon for console players. I believe a majority if not all these functions are available as add-on for PC. And I do not know anything about coding so these 'simple' functions may very well require extensive work on the back end so not so 'simple' after all.

1. Inventory management customization->#1 thing!
-give players the ability to organize their inventory in various ways...most importantly by Armor Set. It would be amazing to see a heading of say "Burning Spellweave" then have all your Spellweave pieces under it. Or sort by quality, weight, weapon/armor/jewelry type.
-give players ability to search bank/crafting bag using keywords

2. Extend the player spec sheet to encompass more stats
-with so many passives adding/subtracting to various stat categories it can be difficult to know what exactly you are working with
-stats such as armor/spell penetration are a fundamental part of the game yet there is no way of adding this up outside of manually. Yes it's possible and not all that hard but so is knowing your resistances, stamina and so on but these are easily accessible.

3. Quick slot different armor/weapon/jewelry setups
-Tank setup, NB gank setup, random theory craft setup, and so on

4. List more than 30 items in the guild store....just sayin'

5. A notification in Cyrodiil when you get a kill or make the killing blow
-Maybe a 'you just killed a Warden!' notification (that is the 1st Warden to die in Cyrodiil hehe)

6. A set rental/test system
- A system of some sort where you can test different sets but for a cost.
- Make it so you can use the equipment for testing only in some sort of testing arena.
- Hell break off one of those cool areas in Cyrodiil no one ever goes and re-purpose it (great idea me!)

OK I am bored now. And I will likely forget I posted this until my next deuce so until then...
