Well, as it is now, when you press the Apply button, the OK button is greyed out. This is, if not exactly
confusing, at least a bit distracting. I'd expect the OK button to be active in this case, as it does in Windows dialogs aswell. The button sequence Apply->Cancel to save and exit the editor is just weird.
As a side note, it feels like REAPER starts up even faster now than before (which already was way faster than many other programs I use)
