I love the new menus and features.
There is one bug/issue I'm having, however.
I keep getting an "Image Failed to Load" and I don't know why (as the file works fine in 1.4), and then the error message stays on the screen until I close it.
EDIT: I managed to save a new version of the image and that seemed to fix it. Not sure why, but oh well. The "Image Failed to Load" message still appearing on the screen seems like a wrinkle though that needs some ironing out.
