Hello. I have 2 ideas:
1. I would love it if you added the option to control how much the volume changes with one press of a configured button: eg. increments of 2, 5 or 10. Currently the increment is way too little to be handy on a mouse button.
2. I'm using a MX Vertical mouse which sadly doesn't have a second wheel on the side that I could use to control volume like the Master series. As an alternative, I set up a gesture key to turn the volume up when moving the mouse right and down when I move it to the left. However, with my mouse sensitivity being pretty low and desk space small, I can only change the volume by about 5-15 pts per mouse movement, which is very annoying! I'd love it if you added a separate mouse movement sensitivity option just for gestures.
