This is a great application and I love the direction it is going. I would say, since the MX Vertical Mouse is not yet a supported device for this application, what I am hoping for is when this device is added I would like to see the feature to switch between devices the MX Vertical is paired with be removed from the bottom of the mouse and moved to the top where all the other controls are. This will allow myself as well as other users avoid having to pick the mouse up in order to transition between devices. the MX Keys does the perfectly where all I have to do is select between 1-2-3 to chose between devices paired with my MX Keys, I would like to see a similar feature added to the MX Vertical. Thank you. Other that, this is a great application and two amazing devices!!
