I do most of the work in the Editor window, editing midi notes, and often I want to listen how the instrument part I've made sounds in the mix, with or without some of the other instruments. To do this, I have every time to close the Editor window and switch M/S buttons in the arrangement view, then open Editor again to continue editing. Another way is to switch M/S right in the editor by clicking channels one by one, but this is nonsense. Can we have the M/S buttons in the Editor Track List, right next to visibility buttons? It would be such a time saver to mute and solo tracks without leaving the Editor. Thanks.
