I have a MX Key and a MX Anywhere 3.
Both are tied to the same computers for fast switch keys (1, 2 or 3).
It means if I choose computer 1 on keyboard and choose computer 1 on mouse both devices will control the same computer.
Here comes the enhancement idea: It'd be helpful if when I select computer 1 on keyboard the mouse automatically also changes to computer 1 and vice versa (if I select computer 1 in mouse computer 1 also would be selected on keyboard).
Computer 1 is my personal computer so I have total access to configure it as I want. But, computer 2 is a company's machine and I can't install Logi Options+ to have advanced features like Flow. And, computer 3 I normally use with Ad Hoc machines I temporarily using (so also not prone to install Logi Options+).
