When you switch your keyboard between computers using the key at the top, it should automatically switch your mouse with it.

I hate having to bounce my mouse to the side of the screen hoping it will flip from my PC to my Mac. It's equally as frustrating when you've switched your keyboard over, only to be reminded that your mouse either needs to hard slide to the left, or be lifted up so you can push a button on the bottom.

This should have been a basic feature from the very beginning. Very poor UX oversight.
