Accidentally pressing the letter "A" and then wondering what happened to the Record and Monitor buttons is a pitfall that probably every Studio One user has run into and it's certainly one of the top recurring questions on Studio One forums ("My Record button is gone! How do I get it back?").
This request is for a popup warning that says something like “You pressed the [A] key, which puts the system into Automation Mode. Don’t worry, that’s not as scary as it sounds, but it does mean you won’t see the Record or Monitor buttons until you press [A] again. (Click here to never see this warning again: □)”
That’d save new users a little frustration as they learn their way around Studio One.
