dsh-jumpbar

User message jump bar for the DeepSeek Harness (DSH) web GUI.

A minimap-style dash strip floats at the right edge of the conversation scrollport. Every dash maps to one of *your* messages (kind user only, not steering bubbles), positioned by the message's real vertical ratio inside the transcript. Hover a dash to preview the message content; click to smooth-scroll the message to the top with a short brand-color highlight.

Install

dsh plugin --profile web add dsh-jumpbar

Restart dsh web, then open any conversation with at least one user message — the strip appears on the right edge of the chat column.

What you get

• Minimap-style positioning — dash spacing reflects how messages are spread

through the transcript, so you can see at a glance where each user message sits. A thin viewport marker inside the strip tracks your current reading position.

• Hover preview — a bubble beside the strip shows the message's text

(action buttons and clock are stripped from a cloned row; the product DOM is never touched), and the matching message row is faintly highlighted in the transcript. Keyboard-focusable, no pointer required.

• Click to jump — smooth-scrolls the target message to the top (12px gutter)

and flashes a highlight overlay at the settled position.

• Drag to scrub — press the strip (between dashes) and drag to move through

the transcript; pointer capture keeps the gesture alive outside the strip.

• Live updates — new messages, loaded history, window/column resizes, and

session switches recompute the strip via MutationObserver + ResizeObserver with rAF throttling; stale previews and cache entries are dropped on change.

• Zero footprint — hidden entirely while no user message exists; floats in

shell.overlay, never squeezing the conversation layout.

How it works

Pure browser-side plugin. It registers one shell.overlay entry and measures the product's own data attributes ([data-conversation-scroll], [data-chat-flow-kind="user"], [data-chat-anchor-key]), so it needs no host logic and changes no product code.
