That would be vastly preferable, more usable and useful.
And apologies, I should not have responded to a request for a built in-feature with info about implementing it as an add-on. I had previously suggested making a new extension type as a stopgap for accessibility features which the development team has not implemented, and was pointing out that a draft-editing UI would also be greatly superior to a chat-in-chat UI here. It was offtopic, and I’ve split that into a new draft-editing extensions thread now.
