Thanks for the detailed analysis. They match what I'm thinking about.

Are you sure after limiting AreaBottomEdge the driver can still detect
X/Y from the buttom area, which is needed for deciding whether it's a
left or right click? I'm reworking my ClickPad patch to remove the
border control logic.

I'll try to test the jumpy cursor issue with EmulateTwoFingerMinW=5 on a
Lenovo IdeaPad S10-3t. If that works I won't have to maintain the
JumpyCursorThreshold patch anymore.  :)
