More accurate description of features. How is it achieved? Smooth scrolling for instance, how are you achieving this? Different scroll speed, software implementation etc. Scrolling mode, how does that work exactly? I think there's some electromagnet creating resistance, accurate descriptions help users make more informed decisions on what to choose instead of trying to figure out by testing and speculation. It's important to remember not to treat people like they cannot understand, those who care about the settings will gladly read to understand how it works and how the settings are achieved instead of having to play a test and guess game. :)
