Some mainstream Microsoft products already support side scrolling inputs from mouse inputs that are capable of doing so with a notable exception of Excel. Ironically, I feel Excel would benefited the most of this feature. I understand that a user can side scroll with the Scroll Lock enabled but if the user already has their hand on the mouse to scroll vertically then it would make sense to allow horizontal scrolling.
Again, this capability is natively there for may popular applications with the notable exception of Excel.
Thank you for your consideration.
Amazing that this is not fixed and not imbedded in Windows OS.
