🖱️ Usage

Right-click the target; the menu appears exactly at the cursor.

Surface	Menu items
Produced-file chip / inline reference / tool-card link	Open · Open containing folder · Open in editor ▸ (detected editors) · Open with another program… · Copy path · Copy relative path
Sidebar workspace (project) row	Open containing folder · Open · Copy path
Sidebar session row	Open containing folder · Open · Copy path

Platform behavior:

Windows — "Open containing folder" opens Explorer with the file selected (explorer /select, ); "Open" uses Invoke-Item; "Open with another program…" opens the system dialog (rundll32 shell32.dll,OpenAs_RunDLL).
macOS — reveal uses open -R; open uses open.
Linux — reveal/open use xdg-open (desktop only).
"Open with another program…" is Windows-only and hidden elsewhere.
When the Host cannot open paths (canOpenPath = false, e.g. remote web access or headless Linux), all OS-dependent items are disabled; copy items keep working.

🔧 Configuration

Add a custom editor: edit the EDITOR_SPECS table in plugin/host.js and mirror the entry in lib/index.js — each spec has commands (PATH-resolvable names), exeNames (GUI executables next to a bin/ script), and installs (absolute install paths).
Menu text: edit the zh / en dictionaries in plugin/client.js.
Theme: light mode uses harness alias tokens; dark mode colors live in MENU_CSS (data-fm-theme="dark" block) in plugin/client.js.
