Hey small development process that I like to follow: I prefer to have an issue open before a PR is opened. @cguedes could you open an issue for a Lexical prototype so that we can discuss high-level thoughts there and code-level thoughts here in the PR?

@hammer do you think we should link to #4 or create a specific issue for Lexical linked to #4?

Up to you!

Another small point on development process: it'll be easier for everyone if we create branches on this repo (rather than a fork) for PRs. I think everyone should have push rights? Or can easily be given them.

Wow a lot of features already implemented! A few thoughts:

• We can resize components now. How easy is it to collapse them entirely, or re-arrange them?
• What is the difference between "Uploads" and "References"? Do we want them to be separate?
• If we wanted to have multiple documents, is it easy to add them as tabs as in VS Code? Long term this creates questions about the scope of references and AI interactions. Nothing happens if I click "file2.txt", e.g.
• ">" to create a collapsible block behaves weirdly
• "Markdown" toggle does not seem to be able to toggle back.
• Inserting references already, nice! It would be nice to be able to insert from Markdown using the appropriate syntax.
• Vertical alignment of Lexical toolbar is odd, it's covered by the title bar and doesn't show fully even in fll screen mode.

Closing this in favor of #23 that integrates Lexical using the most recent codebase.
