Thanks Herman, glad you enjoyed it! I agree with your suggestion, having the middle finger + thumb for tap and index finger for the movement will mitigate the cursor drift. The only reason I used index finger + thumb is so that it is like the Apple Vision Pro input. But definitely could be an improvement.

Unrelated, but shoutout to bearblog. My first blog was on bearblog, which made me start writing. Although I later ended up self-hosting my own blog.
