Ok, so I just upgraded to 10.1. Here are some issues. I hope I'm just missing something. 1) I can't adjust the width of the LIBRARIES frame. I can hover over the line and it looks like it should adjust (i.e. the cursor changes) but I cannot change the width. Weird. 2) I don't seem to be able to adjust the locations of the difference frames like I could in the prior version. I used to like having the playback window on top and the window with the frames/video on the bottom. Now everything appears to go left-to-right. Am I missing something? It seems weird that Apple would remove this flexibility.
