The side buttons on generic mice work really well for navigation in Windows... but not so much in macOS. By default they basically do nothing, and most software that claims to fix this problem (USB Overdrive, etc.) only binds the buttons to keyboard shortcuts with mixed results. While testing the Logitech MX Master, I noticed that unlike every other mouse I'd come across, its side buttons were acting in a suspiciously Windows-like manner on my Mac. (No blinking menu bars. No occasional destructive behavior. No mis-targeted navigation commands.) I decided to investigate this phenomenon in hopes of porting the behavior to all my other mice, and to make a long story short: it works! Really well! (Under GPL!)
It'll never work! But it does. This isn't steel with a plastic or teflon coating. This is unadulterated, hot-rolled, mild steel. It's worked into various shapes, finished smooth, burnished, and customized with your own mark, if desired. The final surface treatment enhances the function of optical and laser mice while reducing friction between the pad and mouse. The pad, over time, develops a patina that improves the feel and optical pick-up. Beyond the shapes offered, I can customize your pad design to whatever fits your desk, or imagination. Customization is encouraged.
