I have given this some thought and investigation and I don’t think there’s much to do about the danger aspect. It seems that there is both a bug and a caveat here. Using your connection 1 and 2 example where connection 1 has Editor and connection 2 is active…
Bug: When you interact with the Editor whether it be clicking within, typing, or executing some action using shortcut the connection bar for connection 1 does not toggle to indicate that it is active.
Caveat: What you see as the active window does not match what you see as the active session. This is just how it is and has always been. Connection colors would help here as long as you use different for connections 1 and 2.
I have the bug fixed for next beta so that the active session indicator is correct. This makes it more obvious if your first interaction with the Editor is by clicking within or text insertion. If you go straight for a shortcut or click on an Editor tool button you’ll notice nothing until the moment you release the key/button.
