Nice to see a good kext for Elan touchpads.
I have one issue which annoys me though. Whenever I slide a finger off the top of the touchpad, the cursor will reset to the center of the screen. I'm using a V4 touchpad.
Are you going to publish the sources? Your github repo hasn't been updated in some time. I would like to have a look through it (as this is all based on open source code).
