It would be great if pressing the Easy-Switch keys on the MX Keys keyboard also switched devices for a linked mouse like the MX Master 3. Flow allows you to switch both, however it's sometimes difficult to get it to work, especially if each computer has multiple monitors, so I often find myself manually switching the MX Keys keyboard and then lifting up the MX Master 3 mouse to press the button underneath to switch devices, which is a bit cumbersome. Alternatively, adding a Hotkey or assignable button switch both using the MX Master 3 mouse would be helpful too.
