Hi, overall, this app is amazing, and I love my MX Master 3S. If anything, it could be a bit more intuitive in custom settings, as some options are labeled differently here than in specific presets. For example, “Switch between desktops” in Window navigation and “Desktop left” in Custom. At first, this made me think that some options were missing and caused some confusion.

Also, I know this isn’t about the app itself, but it would be great if you could add a rest for the ring and pinky fingers and increase the pulling rate in the next MX Master 4.
