Tool panels are an absolute nightmare in Indesign. The detection of, in which direction the panel should open is buggy. I have the Application Frame on my main screen and the tool panels all on my second screen. The setting panels never pop up into a direction where it's handy. They just go outside of the screen.

Also, when having some tabs open and some collapsed, it's an absolute nightmare to open a different one. InDesign does not care about how big your screen is. It just makes the panel bigger and bigger and go out of your screen making it impossible to access the other ones, or even the one you wanted to open. You end up opening and closing or resizing your tool tabs over and over and over again. Have you never heard of scrolling?
