DeepSeek Harness Sidebar & File Preview Plugins
If you came from ChatGPT’s right-side panel and wondered “where can I find a DeepSeek Harness plugin with a right-side panel to select or preview files?” — you’re not alone. This guide maps the sidebar and file-preview plugins in the directory so you can stop hunting.
The short answer
DeepSeek Harness does not ship a ChatGPT-style right-side panel out of the box. But the plugin ecosystem covers it well:
- Full sidebar workbench → DSH-better-sidebar
- Dedicated file explorer → dsh-file-explorer
- Web UI polish pack → dsh-web-ui
Install any of them with one command, e.g.:
dsh plugin add github:omdsh-dev/DSH-better-sidebar
The three ways to get panels and previews
1. DSH-better-sidebar — the all-in-one workbench
The closest thing to a “right-side panel” today. It replaces the sidebar with a workbench that includes:
- File rendering and editing (click a file, preview it, edit in place)
- A built-in terminal
- Git views
- Subagent panels
- A plugin API so third-party plugins can register new sidebar pages
If you want one plugin that covers the ChatGPT-style panel experience, start here.
2. dsh-file-explorer — the file browser
A focused file explorer: file tree, markdown preview, syntax highlighting, in-panel editing, and VS Code integration. Pick this when you specifically want select-and-preview files without the heavier workbench.
3. dsh-web-ui — the visual polish layer
Not a panel per se, but it bundles skins, a task board, Git graph and layout improvements that make the interface feel more like a modern IDE. Often installed alongside a sidebar plugin.
Scenario: I want to preview files while chatting
The typical flow:
- Install DSH-better-sidebar (or dsh-file-explorer).
- Open a file from the tree — it renders in the panel.
- Ask the agent to edit it — the panel updates as the agent writes.
- Use the built-in terminal for anything that needs a shell.
Related UI plugins worth knowing
- dsh-focus-chat — a stripped-down, easy-to-read conversation view when you only care about final outputs.
- dsh-milestone — a Git-style timeline of your conversation, hover for metadata, click to jump.
- dsh-turn-rewind — rewind conversation and workspace state when an agent run goes sideways.
Browse the whole UI Enhancements category for more, or search the directory for sidebar-related plugins.
Bottom line
The ChatGPT-style right-side panel is the most-requested UI feature in the DSH community, and DSH-better-sidebar + dsh-file-explorer are the two plugins that deliver it. Install one, restart the UI, and you’ll have file selection and preview right next to your conversation.
