First off, I absolutely love mx keys and mx master. great products. One thing I think that would make this them better is using the easy switch keys on the mx keys to switch to other devices but also switching to for the mx master as well. For example I if I am using both my mouse and keyboard on my PC and want to switch to my ipad I would like to just switch using the button on my keyboard and have the mouse follow the keyboard to the ipad. Thanks!
