Needless complication
You need to have ONE SOFTWARE to control everything. Instead of "Setpoint," "Unifying," "Logi Web," "Options," and "Options+," you should have ONE PROGRAM that does everything all these otehr softwares do separately.
Get rid of "Logi Web." I can't use it with my browser, and I'm not going to change my default browser just to use a ****** program THAT SHOULD JUST BE UNIFYING ANYWAY.
When I load "Options+," you should just go straight to my default mouse, and that should show all the options I can tweak. I shouldn't have to click "Mouse," "Settings," Pointers and Scroll," and "Mouse Speed," just to change ONE BASIC SETTING. You've made your software needlessly complicated. It's not hard to do, but it is more work, and therefore more frustrating than it should be.
