Muas' All Mighty buttons file is the most comprehensive to date, however many are finding that they lose engine sounds by using it - that's my biggest issue. I'm now in a "catch 22' situation, either I can have all the new planes, minus some sounds, or I can have the more limited buttons file, with all sounds working, but 60% CTD if using the new AC. I think this is the issue most are having....

ceege - afaik, the Magister and the Battle are the only 2 new AC that are not included with the 'All mighty' buttons file.
Also, if you are going to go with UI 1.1, I'd advise making a backup of your entire current game, then start with a fresh install...
