This is great. Customising extra mouse buttons for day-to-day computer use is underrated. I mapped the two side buttons on my mouse to switch virtual desktops, and now I can't live without it. Switching desktops is a three-fingered swipe away on a laptop trackpad, why shouldn't it be as immediate with a mouse? For my home theatre PC (i.e. the intel NUC that's plugged into the TV for netflix), the wireless mouse that's sitting on my coffee table has its side-buttons mapped to volume up/down, which is important - the wireless keyboard has prominent volume controls, but avoiding switching to the keyboard is extra useful in this context. I like my current mouse (microsoft intellimouse), but the prospect of adding three further buttons in addition to the two side buttons I already have, and the realisation that the escape key, specifically, is one of the major drivers of mouse-to-keyboard switches, is making me consider switching to the one in the OP. Though being ambidextrous is a drawback - the intellimouse is an excellent shape.
