Until recently, I was able to dock various tools (e.g., object manager, transformation, text, contours) on the right side of my screen, just to the left of my color swaths. Each tool had its own tab. All the tabs were arrayed from top to bottom. I could easily select one of the tabs, and that tool would fly out.
But something happened a few weeks ago, and now the only tool I can dock there in the same manner is the object manager. If I try to dock another tool, such as transformation, it does not show up with its own tab. I have found that if I play around with all the arrows at the top, I can make transformation appear to the left of object manager, but this arrangement is very inconvenient. And to collapse that tool, I again have to play around with several arrows.
I want to get back to the previous arrangement. Can someone tell me how to do that?
