Feature request: Give appropriate ids and class names (e.g. "message-author", "message-content", etc) for userstyle writers

Kind of a low priority thing. We would probably not be actually using most of those since that is not the tailwind way. This is for userstyle/userscript writers' convenience.

Yeah, happy to do this stuff. I'm keen to see some of the user styles to potentially add some options for styling. For example there is an open PR to move the user messages to the right which would be okay to have as an option.
