with the latest update your software ha become useless.
I'm a design engineer, and I did find very useful to be able to remap the mouse buttons. When I say remap I don't mean shortcuts to lower music volume, or to put a like on facebook, etc. etc.
As engineer you need simply to put on the mouse some keyboards buttons: in my case it was F3 and F8. With the new update, it is not possible anymore. Too bad.
