Oh yes! Or just clicking the labels on the left, and the matching editor will be shown. So no need for having tabs. And "Filter Env" to "Cutoff", only showing a slider, too. So you could do it in oo way or so.
Maybe, but cutoff is actually two sliders which sets the cutoff range so it's a different type of control to the others. Doing this for each other slider with a breakpoint is going to clutter the GUI so I will need to think it through some more.. I want a balance between speed and functionality
