I use the app menu (context menu) A LOT. It saves me the hassle of right-clicking on the mouse, and I am more efficient with it. I love the MX keyboard, but I HATE the fact that the app menu button was placed so far away in the upper right corner. Why can't we reprogram the CMD/ALT or OPT/CTRL buttons on the right side of the keyboard, below the right shift key? Giving us two CMD/ALT keys on either side of the keyboard is a waste of valuable button real estate. Thank you.
