For me, this has always been the problem with Blender. Underneath all that weirdness is a very powerful program. I know there is a lot of power there because I have seen all the wonderful things that talented people have done with it. Unfortunately life is too short and I just don't have the time to fight with it. I have picked up lots of useful MoI tips on the forum (thanks guys) but don't feel I actually needed to learn MoI to use it because almost everything was intuitively obvious.

The Blender devs are between a rock and a hard place really. I suspect much of the current user base won't like the changes. Seems to me that the only way they can move forward is to provide classic and custom GUI's.
