I currently own an MX Master 3S mouse and MX Keys S keyboard, and I've owned various MX Master/MX Keys keyboards over the years. I chose them because they support multiple devices. I'm often sent laptops by clients, and I don't have the option of installing Logi Flow software on these devices.

1. Move the device switch for the MX Mouse to the top or allow device switching to be assigned to a custom button. The multi-device option is not useful on the mouse since switching devices requires pushing a button on the underside of the mouse. (The device switching on the keyboard is perfect—the device selection buttons are easily accessible.) The Triathalon has the selector switch on top, but it's not nearly as functional or ergonomic and isn't an option for me.

2. Allow the option to connect or integrate an MX Keys keyboard and Easy-switch Mouse so that the computer they're controlling is selectable from either device (keyboard or mouse). ie, if I select device 2 on the keyboard, synchronize the mouse to control the same device. This would make it easier and more fluid for a user to switch control since they wouldn't have to change two devices.
