Control Surface Studio handling questions (for OSX)

Hi again 🙂
I have been watching a few of the tutorial videos and am seeing that it must be possible to just click on knobs and buttons in the virtual visual representation of my physical controller when assigning functions, instead of scrolling to the particular knobs and buttons in the controller input list. The blue square then appears on that said button or knob. However, when I click on any button or knobs in the CSS, nothing happens. I still have to go and select in the controller input list. Does this sound like a bug?

The other question is: How do I quit CSS? Usually there is a “Quit…” option, or if anything else, Command+Q works. Nothing… I have to force-quit the application. Again, is this a bug?

I hope I can figure out these things, remotify seems like a super powerful tool!!

Thanks so much !
