Make it so the Stop command doesn't disconnect the bot when stayinchannel=true

It would be nice if the stop command didn't disconnect the bot from the call when I have stayinchannel=true. Either that or make a separate command to clear the queue

No file or test is identified in the issue. Start by locating the Stop command and the handling of stayinchannel=true, then determine how queue clearing and voice disconnection are coupled. Done means Stop clears the queue without disconnecting when stayinchannel=true, or a separate queue-clearing command is defined.
