Idea: minimize all visualizers button

[jbscherrer]

Oftentimes I have a million visualizers open at once that I'm monitoring for an experiment, and they are covering up the workflow in the main window. If I want to access the workflow while it is running (say to enable yet another visualizer), I need to minimize all of the visualizers by hand because they always have display priority over the main window. It would be convenient to have a "minimize all" button so I don't have to do this for 20 different windows.
