So far, this looks awesome! My only quibble so far is actually just install related... I've never been a fan of installers that play sound or music while copying files with no way to turn it off, especially with such a long process. I know I usually launch long installers and do something else, however the music played in the background (while nice) is so loud and ominous it dominates my system while the mod installs.
Great work on this!
