I recently found this very useful UI update by "fire&ice" that allows NWN2 mini-maps to be bigger than their original design. The UI builder has a number of modifications that allow for 120%, 150% or 200% increase in size with larger map pins if required. Furthermore, the mini-map can be made to double in size again while in the game simply by double-clicking on its top bar. This is a really useful addition to the game and I recommend it to all my players. And don't forget to vote if you do use it.

On the subject of maps, I have improved the quality and enlarged the size of the "Maps Within Maps" video. Check the new video now.
