I think the logic addition is great. I particularly like the ability of the cursor to stay in sync with song which gives me a good work flow when I am composing and adding parts. i don't have to remember the chords which is particularly helpful when going back to songs.

A couple bugs I am having is that the AU seems to forget where the real tracks and drums are. I also have to rebuild the lists for the drums and RT as well as the styles after i reopen them.

I think i read that the resizing of the app also was something that would be remember but i am having to reset the size every time.
