Let's say I'm building a stack overflow style editor (you type markdown and it gets rendered in a preview tab) -- would there be any reason to use lexical?
You could also roll with a `<textarea>` but that can be limiting if you want additional functionality further on down the line – such as mentions or inline markdown shortcuts.
And is the idea of mentions that we can use Lexical to provide nice things like pop-up auto-complete of a username / automatically transform the username into a link inside of the input text?
Live preview = the editor is WYSIWYG but the storage format is Markdow
