dsh-question-jump-bar: Conversation Interaction Enhancements (Follow Up by Selection, Edit & Resend)

`dsh-question-jump-bar` is a DSH Web plugin maintained by popeye1113, designed to provide a conversation experience similar to reasonix. It features three core capabilities: after selecting text, clicking a floating button opens a reasonix-style quote panel for follow-up questions; a pencil button in the bottom-right corner of each user message allows editing and resending the message; and a custom renderer supports parsing follow-up quote markers. The plugin is compatible with DSH 0.1.2+ and the new turn navigation mechanism. Users can install it via the official command; when using it, they can select text to ask a follow-up question or edit a message.
