I have an "M575 for business" (using Logi Bolt) and since the device itself only has vertical scroll, it'd be really nice if there were an option to scroll horizontally with the help of a setting in the Logi Options+ software - either bound to one of the side buttons, or perhaps a middle button "use trackball to scroll in any direction" feature. Unfortunately no such features seem to exist. Puzzlingly, the M570 mouse, which also lacks direct hardware horizontal scrolling, does have sufficient features in the software. Please consider enabling/implementing one of my earlier-discussed features for the Ergo M575 too.
