The update to MX Anywhere's ability to hold down a side button and use the scroll wheel for horizontal scrolling gave me a cool idea for extra features to the MX Mouse range.

That is to hold down a side button (or any button for that matter) which creates an 'alternative' option for other buttons. Kind of like the 'fn' key function to change mouse button behaviour.

An example of this would be: Vertical scroll on the MX Master, then hold down 'Forward' or 'Gesture' button, now when scrolling it can adjust the volume up/down. Obviously this is just an example that I would 100% use (right now the 'Horizontal Scrool Wheel' is being used for volume, which prevents actual scrolling).

This would unlock soooo many more features to the MX Mouse range since it's kind of like holding down a keyboard modifier key (Shift, Command, Control, Alt, etc) then adding alternative functions to each button/wheel
