dsh-client-ui-quote

Select text in a DSH conversation, a file preview or the terminal to quote it: the floating bar offers Comment, Add to chat and Side chat, and Alt+Q / Alt+C / Alt+B do the same three things. The quote - and its comment, kept in the same chip - is inserted as a native reference chip, and a sent quote stays one rounded capsule in the message that expands on click and can be copied. A hover card can jump back to the message a quote came from, and the right sidebar carries a quote list page that searches every quote of the session, jumps back to any of them and exports them as Markdown. Side chat writes the quote into the composer of one dsh-better-sidebar side thread per conversation without sending it, and that page can bring the thread conclusion back into the main composer or export it as a file. A sent quote can also be revised: the card puts its old comment back in the comment box, the corrected quote is sent as a new message, and the old capsule is marked as superseded (the transcript itself is append-only).
