In Everquest 2, the user Interface (also abbreviated to UI) is a very special feature or even a cool tool that allows its users to tweak and customize the User Interface as they wish.

Within UI, users can also view many useful and important things in front of them, while playing the Everquest 2 game such as their own character portrait, pet portrait, party member portrait, spell and ability icons, talent icons, minimap, chat log, combat log, action bar, pet action bar, interface panel and many more. All of these can be easily modified or adjusted to better suit the users' own specific needs as much as possible.

Furthermore, mods and add-ons are also much preferred to be used to add a set of extra and new functionality to the already existing user interface to better fit in their style of playing the EQ 2 online game.
