Something I just noticed, and I'm not sure if it's the intended behaviour or a bug.
If I add a machine, the corresponding track in Reaper's interface is unnamed. As soon as I rename the machine, it updates the name in the track-view.
Also, a little feature request: when editing the volume and/or pan, would it be possible to reset to default settings by double clicking? IE: Double click on pan, and it resets to Center.
