Hello! Currently, I own both the Logitech MX Anywhere 2 and recently own the MX Master 3s.

I find myself missing a particular feature from the MX Anywhere 2 which I found valuable in my everyday work. Notably, it's the capability to trigger horizontal scrolling by pressing any of the lateral buttons in combination with scrolling the wheel.
Adding this feature to the MX Master 3s would provide these benefits: (1) it would standardize the user experience across both mice, enhancing ease of use especially for those like me who regularly switch between the two models. And (2) it would free up the dedicated horizontal scrolling wheel on the MX Master 3s for alternate functions like switching sheets in Excel or tabs in a web browser.

Thanks.
