I can handle the new UI but, I have a few problems and I don't know if its fixable and I just haven't figured out how yet, or is it not possible?
1) The panel on the right. I can't drag toward the center of application to make the panel bigger, nor can I drag out to make it thinner. It is just locked in one place which is annoying. Sometimes I want more screen-estate and you know sometimes I just can't see clearly what those stamps are because they are really small in the panel. i literally had to stamp a bunch on a canvas to see what they looked like.
2) Still with the panel - why can't I have my effects panel and quick style panel open at once? that effects area is CRITICAL and yet it sits in the lower right corner looking unimportant next to properties. I even tried to pull it into the menu bar but couldn't. It should be ON TOP, or make the panel on the right have more division sliders so i can get to both easily. AND please, is there a way to undock the panel maybe? undocking would be awesome.
3) So like many others I couldn't find anything right away. Then I figured out how to customize the menu bar the way I want, so I was excited - and went to town dragging every icon imaginable to my menu bar - then ----- i ran out of ROOM. Is there a way to make two toolbar rows that I don't know about? Is there a way to undock and redock the toolbar.
4) Finally have issues with the user intuitiveness when modifying/working with screenshots etc in the canvas. I don't know how to explain it but it doesn't work right anymore, what i want to select doesn't select on click, when i want to move things around and one goes slightly on top of another item i just moved, I now have to preflatten first - it isn't 'smart' like it used to be, and working with text is nightmare, or toggling between an object and a text box the selection functionality is messy now.
