You can download several customized UIs for NWN2, including this Improved UI, this UI Messagebox Fix, this and this Slim Health Bars Fix.

As such it is highly customizeable, and considering a range of people are not happy with the default interface, this is a good thing. The user interface (UI) in Neverwinter Nights 2 is scripted in XML, and found under the \Program Files\Atari\Neverwinter Nights 2\UI\default folder.

If you're not interested in making a mod for NWN2, you can read about and download free community-made modules here, here, or here among the many places which are distributing modules. There are some problems with the Toolset at the moment, however you can discuss them with other modders here. The instructions for using the Toolset are in your \Program Files\Atari\Neverwinter Nights 2\Documentation directory. This gave the game a very powerful capability which is continued with the use of the Neverwinter Nights 2 Electron Toolset that comes with the game. Just like modules in the old pen-and-paper D&D, you can create entire new worlds and storylines to go with them. The original Neverwinter Nights became extremely popular because it allowed the community to create a range of custom modifications, or more appropriately for the D&D world - Modules. Important: As of the 1.23 Patch, users no longer need to keep the DVD in the drive to play - the disc check component of SecuROM has been removed from the game. Hopefully Atari will listen to the various requests from legitimate purchasers of this game to at least remove the CD/DVD check component of the copy protection in a future patch, as it is annoying and only punishes paying customers. I can however say that SecuROM can cause issues, particularly startup problems - see for details. For legal reasons I can't provide any details of a No-CD or No-DVD, or other methods of bypassing copy protection.

Neverwinter Nights 2 requires a CD Key and also uses the SecuROM copy protection system, which requires that the CD/DVD be kept in the drive while playing the game.
