dsh-sidebar-plus

DSH's sidebar file preview has always been a read-only experience: Markdown renders as styled text with no source view, no line numbers, and no way to edit in place. For any other text format you get a plain rendering but still no quick search, no font-size control, and no editing shortcut. Changing a single config line means closing the preview, opening a separate editor, saving, and switching back — a workflow that shatters focus.

dsh-sidebar-plus fills those gaps with four focused features. It adds a Source Edit view for .md and .markdown files with left-side line numbers and syntax-aware colouring of the raw Markdown. It wires an Edit / Save path into every text format (Ctrl+S to save, Esc to exit, with a conflict dialog offering Force Overwrite or Reload Latest, and an automatic backup of up to 20 previous versions before any overwrite). It brings Ctrl+F search and A- / A+ font-size controls (plus Ctrl+scroll) to every view. And it adds a toggleable line-number display to the official Plain Text view. Images, PDFs, and HTML are left untouched.

This plugin is for developers who live in the DSH terminal and regularly inspect or fine-tune config files, logs, or notes without leaving the sidebar. Everything runs in a local process with zero external network calls. The hot-swap loader keeps the current version active if a new one fails validation, so the UI never crashes. User preferences are stored only in the browser's localStorage, keeping the privacy boundary clean and predictable.
