Heh, I like this. But I also keep reading that simply holding "good" posture is not helpful, and that changing position (including to slouch, recline, rest on a elbow etc) protects against muscle spasm from holding the same position. I suppose this implementation could help with that too though. Slouch a bit, get reminded to lean back, repeat etc.

I think of the extension as a nice occasional reminder. I personally use it almost like "exercise". Turn it on for a while when I'm casually browsing, and it just helps build a habit of checking my posture. It's just one more tool I use on my health journey.
