Space management in Visual Studio is important. Especially if you have Studio running on a projector, small monitory, or are using the split screen options extensively.
Visual Studio has a couple of running modes, and each of these modes has it’s own memory. So when you’re in Full Screen, Debug, or Normal mode, Visual Studio will remember your window/panel/toolbar locations for that specific session.
I like to run my Solution Explorer on the left in regular and full screen mode, but on the right in while in debug view. This is a huge reminder to me that I’m running in debug mode.
