I love the products ( both mouse and keyboard ) however - One thing that has been missing and making my life hard is the option to program device switch on one of the top buttons of the mouse - Please Please Please - add that option in the firmware. I have literally made my own hack by disconnecting the side bottom thumb button and connecting it to the one that is used to switch the devices. It works but I loose whole set of button options.

THANK YOU for making great products !
