about Session Guitarist Toggle shortcut

I had a lot of problems using it. Makes me feel sick.

1. Pay attention to the yellow area. It's pattern and rhythm. Isn't there a key to keep going or start over with the next chord? Can we just keep going, or can we start over and the sound breaks? Can we design a shortcut to make things easier?
2. Pay attention to the red areas. These picks, fingers, muffled sound, the original sound switch, is there a more convenient way to switch? Or do I just have to re-open a Session Guitarist per sound?
3. Can SONG browser and PATTERN browser be designed and made into separate Windows? I often find a PATTERN in the Pattern browser, and then I don't know which Song browser it belongs to. Can we change that?

Finally, regarding pattern rhythm, I think it should not be left or right structure.
It should be a top-down structure. This will make it easier to see if the back and front are different or the same. I highly recommend adding a trick key to control where to play.
