Maybe I'm not aware of how to do it but it would be helpful to have the option to enable or disable time signature mapping when a tempo map is open. I often make time signature changes or experiment when trying to establish the best metronome bpm for the music I'm working on. I necessarily do not want the time signature changes to be mapped. I don't usually have the Time signature map open unless I specifically want to add a signature change, it's hard to realize that one is even mapping anything. Cheers..
