I'd love the ability to embed content/blocks of text from one place in Lex into another place. That way, I could type something once, and re-use that block of text elsewhere, and when I update that original / or the secondary/tertiary embed, it could update everywhere. I'd also like the ability to edit one embed only and make that able to become its own unique text without updating the other embeds. Roam Research does this well with their 'block embed' feature. It'd be great to have a way to access this w/ keyboard shortcuts. In Roam it's typing "/block embed". This type of feature set would be helpful if you want to empower us to use Lex as more of a second brain. Not sure if that's the direction you want to take Lex but it'd be super cool.
