dsh-layout-control

DeepSeek Harness ships a full-featured Web UI, but the layout is fixed: the composer always stretches across the bottom, and the session header, task bar, and status strip stack on top of the conversation. There is no built-in way to trim the chrome, dock the input to a corner, or isolate a single stream of transcript nodes without touching the source. dsh-layout-control fills that gap as a pure client-side overlay that modifies nothing inside DSH.

The entry point is a draggable circular button in the lower-right corner; it tucks halfway into the screen edge and expands on hover. Inside the panel you can switch between three presets (Default, Focus, Immersive), choose sidebar density (expanded, icon rail, or hidden), and control the composer in three modes (full, compact, hidden) docked to any of four screen corners. When docked, the conversation column keeps scrolling in the centre while the input card and its todo list hug the chosen corner, and a collapsible session-summary card fills the vacated space on the same side. An 8px inner drag handle lets you resize the docked panel between 280 and 560px in real time. You can also toggle individual chrome elements (top bar, status bar, task strip, and other overlays) and filter the transcript stream to show only AI outputs, user messages, thinking blocks, tool calls, task lists, or reply bodies.

Every interaction rides on public services (ctx.layout, ctx.slots) and stable DOM attributes such as data-slot, never on CSS-Module hash names, so DSH upgrades are unlikely to break the plugin. If you are a DSH Web user who values an immersive reading experience, frequently toggles between focus and collaboration modes, or simply wants to dial the interface density to a personal sweet spot, this plugin is a low-risk, high-impact addition.
