Quote - each core just has it's own little region and just sits there idle as its buddies finish the task...

The way they break up the picture is really annoying.  Why not just break up the picture into a dozen squares and give each processor a block in turn?  I have 12 cores just waiting, and waiting and waiting...

Why does doing a bunch of regions instead of the entire picture at once to get better processing speed not work only because they leave a black line around the rendered area?  Fix that and I'd be happy, since it's what we want with multi-processing (hint hint).

When you go up a menu, why does it reread the entire directory structure every single time, and then go to the top of the menu?   I don't add content all THAT often!

Why can't you turn off some of the undo's, like camera movements?  I move to see what happened when I change something, and then have to undo return to the original view to undo a change?
