Thanks Masi! I agree with the points you've made regarding the possibility of changing where the preference option is located. However, changes to any aspect of the GUI requires thoughtful consideration and development because users who are familiar with the current layout will have to adjust to these changes as well. I will add this to the to do list but I will have to discuss this change with my colleagues to determine if the change is worth the potential confusion that some users may experience. If we choose to implement this change than it will likely only be before a new major release.

The logo could be resized to make more room for a preference button however, I don't believe that the size of the logo has anything to do with getting solo/mute buttons working properly or that any of this has to do with keeping/removing the Play button (which actually has a very definitive purpose). I chose to launch the bar settings dialog by right clicking a cell in the chord sheet because at the moment there is no use in showing a context menu with one item that would launch the bar settings dialog. I appreciate all the great feedback!
