The one thing I use the most, and how I found it in the first place is that it allows me to combine key presses with mouse gestures/movements. In particular it allows me to move/resize the windows under the cursor just by pressing a key combination and moving my mouse. Many many years ago I used to use AutoHotkey on Windows for this functionality and was missing it when I switched to Mac.
Another thing I've configured is scrolling through a key press and dragging the mouse. Or opening a floating menu by using the thumb button on my MX Master3.
And that's only mouse functions, I have a bunch of other shortcuts/remappings/automations, many of which run only for specific apps.
Have a look in the forum - it's a gold mine and a lot of people have shared their presets.
Was not aware it is even possible to replace the shitty logitech surveillance software. thanks for the tip!
Can you give maybe an example of a `funky stuff` for the mouse, like those touchpad gestures? i cant think of any, just to get an idea
