I just upgraded my Adobe Premiere, Photoshop, and After Effects. On all of them, when you either save, import or open a document the little window pops up to find it. Before the sidebar shortcut was there. Sunk up with your computer's favorites sidebar. Now I have to go digging through documents and folders to find what used to be an easy click.
HELP! Even just getting to the desktop is annoying.
