I love Logitech/Logi keyboards! I have the MX Keys 5 now, as I've worn out several corded Logitech keyboards.
May I suggest that the desktop icon be programmed to show the battery level? I don't open the app unless I want to see if I need to charge the keyboard. A quick glance at the icon to check the batter level would be very helpful, and likely a decision maker for potential customers. Thanks!
