> Stretch goals: I'll throw in a desktop version as well (mac first).

Makes sense! Because it does force me to context-switch if I have to open a browser to consult my notes. Browsers are notoriously distracting as well.

The browser extension looks good and functions well, but for me it would be more useful as a front-end to an existing note taking app (in my case, Notion).

Another thing I noticed: keyboard events while typing in a note seem to still be sent to the underlying page, which may react weirdly to that.
