I was migrating all my github actions to use uv, but had a typo in my pypi.yaml so it didn't get published to PyPI. My first thought was to publish a zero-change (except version number) release, but ick.

uvx twine upload dist/*

Hey @pfrazee.com who is the best person to direct UX issues to?
Hey @bsky.app I heard it's a hard dev problem to have the app remember where you were when you close & re-open the app. This is currently my biggest UX barrier-- any timeline for when that might get fixed or is there any way I can help?
