Sluggish tool bar
You mean "fix" illustrator this is a problem not a new idea.
When you try to change to the second tier in the tool bar (i.e. from rotate to mirror there is a long lag. It used to be so easy you just slide over now you have to hold the mouse on the thing for 3 seconds and the it pops over to the side then you have to scroll over and release. Why did you make it slower in the most recent version when it worked fine for years?
can't toggle to minus Magnifying glass tool with option key. After just fiddling with a few combinations it works but not at first, every time/
