Yesssss, I love it. I think we should add a quick hover state and probably some icons, what do you think?

Usability question: Lets say you are viewing a specific post, eg. https://bsky.app/profile/echarles.net/post/3lehhnon3ns2t and you switch account via the profile picture menu, will you stay on the same post, or will you be driven to the new account home page?

I have not looked at the code of this PR ... as a user, I would rather stay on the post I was looking at. Pretty sure others will have other opinions :)

No, out of scope for this PR. would be nice though :)

Use state for this instead, it's not legit to modify refs during render.

We have a bunch of code like this, look for prev

This LGTM (and I love it) but wanna hear back from Dan on if we can handle prev state more correctly
