Tested your patch, working well, nice work.

new configure keyword for smartshift v2(0x2111): torque (the current tunable torque in % of the maxForce)

    smartshift:
    {
        on: true;
        threshold: 12;
        torque: 80;
    };

Strange, I’m getting the following warning:

[INFO] Device found: MX Anywhere 3 on /dev/hidraw2:255
[WARN] /dev/hidraw2:255: SmartShift feature not found, cannot use ToggleSmartShift action.

We should merge the SmartShift and SmartShiftV2 features into a unified SmartShift feature. The raw HID++ 2.0 feature interfaces should stay separate though. That way we avoid issues like what @sfllaw described and provide a better abstraction.

Look into how we deal with RemapButton and the various versions of ReprogControls for more details on implementation.

Ping? Merging this would help resolve #174 and #262, even if it could be improved further.

Will look at this again and fix it up for merging, sorry about the delay.
