Well, time to tell you all a few things right?
One major thing I´ve implemented has been the fantasy aspect; sometimes I truly like to work on ideas outside the modern side of the game and it´s a good change when I´m a bit bored of the twins (well, not really hehehe).
So now Selena is a half celestial although it´s not specified in the "normal" game (intro, family, friends, etc). Using the Portal skill she can teleport to an area to train her abilities, but only on weekends and don´t worry, she can´t die. If you´ve played Sacred, you can get an idea with the Seraphim class.
Another thing implemented has been a way to show quick and basic info; as the game is very text driven, a lot of the time you can´t acces the Profile or Handbag menus to know or use things. Now clicking the group name in the quickslot (the green caps ones) you can see some info (be sure to have Options -> Game options -> Feedback options -> Text bubble Full checked in the NWN game).
Here´s some examples
