You'll need to edit some source, but it's not hard. One way to do it would be to override doClose() like this: public void doClose() { pressHideAll(); // hides all the displays removeAllInspectors(true); // kills all the inspectors } ... then make Console.pressHideAll() public. I guess we could expose that method for you if this works. Then you're responsible for making the Console visible again later. The problem with this approach is that the inspectors are killed, not hidden. If you want the inspectors to stay around, you'll need to extract the inspector windows and hide them all (set them to non- visible), then maintain a list of them so you can make them visible again when the Console is made visible. Look at the code for removeAllInspectors() to see how we find all the inspector windows.
