PrecisionThreeFingerDrag VS syngesture

You may be interested in how I did my Windows script for adding three-finger drag[0].

Basically, it is an independent subscriber to RawInput messages that only keeps track of whether or not to send three-finger drag, and posts emulated mouse messages using SendInput. I have a few other scripts that each run as independent userland processes that only monitors their own trigger and nothing else.

Tangentially, not sure if this might serve for some inspiration, but my TPMouse[1] script implemented inertia in a framerate-independent way so that it uses very little resource while having perfect simulation stability.

A previous discussion where I explained the analytic derivation for this low-resource exact-solution damped inertia can be seen in [10]

You'll need to tick the "Other Human-Interface Devices" checkbox and untick Mouse and Keyboard, so that you don't get the driver-synthesized SendInput mouse reports flooding the outputs

I've shared my opinion on why mouse/trackpad handling is terrible on most Linux distributions [0], thanks to an insane obsession w/ rewriting the entire stack and throwing away vendor-provided acceleration curves in order to provide gesture support, instead of just building it on top of the correct, working solution.

More importantly, there is a solution for fixing this and I've done my part by open sourcing a multi-touch gesture support that's driver-agnostic and runs on top of the vendor-provided drivers w/ their correct acceleration curves [1].

(But TBH I don't know if this applies to Apple's trackpad because I don't know if there are any first-party drivers w/ proper acceleration curves for Linux or if they've all been poorly reverse engineered.)

I wrote a general purpose multitouch daemon w/ gesture support for Linux that works with the existing input stack (i.e. doesn’t require switching to evinput), if anyone is interested:

Regardless of software (touchegg + touché, fusuma, libinput-gestures + libinput-gestures-qt OR gestures, gebaar-libinput, gebaar-libinput-fork, syngesture, gestures), which gestures do you actively use on your Plasma desktop?
