Introducing the DeepSeek Harness (DSH) Conversation Index Plugin

The DeepSeek Harness plugin dsh_chat_index is designed to address the difficulty of navigating long conversations. It provides a visual dot index on the right side of the conversation area, with each dot representing a user question. Users can hover over a dot to view a content preview, click it for smooth navigation, and their current reading position is highlighted. Built on DSH's default 50-message window, the plugin supports paginated on-demand loading of older messages without interfering with thinking or tool output states. Installation requires only one command, with no build steps; restart after installation to use it.
