I'm not really sure if this feature already exists or not, but it seems like it is not there, at least not by default, so I am posting it as a suggestion. I would like to receive a pop-up window as sort of a warning or a request for confirmation when I try to switch channels with "Continuous Transmission" still active.
This is a feature related to privacy. I may be willing to keep continually transmitting with one friend in a specific channel, and at the same time I may definitely want to switch back to Push-to-talk mode as soon as I leave that private channel and go to a bigger channel or so. Sometimes I may forget to stop the Continuous Transmission, so it would be very, very useful for me to receive such a pop-up or warning or confirmation from TeamSpeak whether I'm sure I want to change channel and keep Continuous Transmission active.
