dsh-conversation-landmarks: DeepSeek Harness Long Conversation Navigation Plugin

dsh-conversation-landmarks is a DeepSeek Harness Web community plugin maintained by mantonlove, designed to solve the pain point of repeatedly scrolling in long conversations. Licensed under the MIT license, this plugin adds a fixed, vertically centered landmark bar to the left edge of the session workspace via an official extension point, helping users quickly locate user tasks and their corresponding replies. Its core features include automatically displaying the landmark bar when the session contains at least three user tasks; supporting hover previews of user requests and the latest assistant replies; and allowing users to click a landmark to intelligently load history and smoothly scroll to the target message, ensuring it is fully visible. The plugin adopts a non-invasive design; it does not modify DeepSeek Harness source files, execute its own network requests, or collect telemetry data. Installation requires DeepSeek Harness.
