very nice in general. MX master 3S work like a charm

feature request:
1. not only it should be able to app specify for the gesture setting, but also allow smart identify of task. eg when mouse hover on a video, audio from webpage or youtube the mouse wheel should sense there is progress bar and let the thumb wheel to fast forward or backward. It should then switch to horizontal scroll when you hover on a wide list, maybe in window explorer or excel, anything able to scroll horizontally via shift+normal wheel, should be able to execute by thumb wheel in this case.

1. I need backup of the hotkey for the device completely with different set I can switch easily, just like smart action is allowed to switch on or off. They are sitting there anyway and allow me to turn it back again easily.

3.please allow smart action in gesture too.

4.adding new software for different set of hotkey should use general hotkey as a base. or just like i mentioned let me save the setting as default or setA, setB, then let me choose it so i can modify base on it.
