Thanks!

Exactly. The mental model thing is brutal. You know every corner of the app, so everything feels obvious. Then you watch someone use it for the first time and they're completely lost. Need to do that more often, perfect way to learn.

And yes - QR sharing was about bringing back that "here, just take it" moment. Sending library export as JSON, explaining how to import... too much friction. Scan and done feels right.

The mental model is usually what I want most (and often find missing) from onboarding. If you give me the model and vocabulary I can find the buttons myself. If you teach me 1 workflow I'm probably helpless at doing anything else.
