I'm not sure that this is quite a feature request, but rather a potential solution to a window rendering bug in some VST hosts. This is about some VST hosts causing the GUI contents to always use the default resolution of Stereo Tool in a container window that defaults to (or remembers previous setting of) a different resolution.
How about adding a switch that forces it to start up in Full Screen mode?
If it already is intended to have the behavior of remembering what your last option was, perhaps it needs to re-check the resolution then redraw the GUI accordingly to the size of the window container upon startup? Or maybe it needs to check again and do a full redraw when selecting something in the left menubar of modules?
Or a key combination to cause it to re-detect the window size and redraw?
I'm just too lazy to keep going back and clicking Full Screen Mode every time i open the gui window.
edit: It would also be cool to have a toggle for 1/4 height scopes.
