Glass preview HTML files on open

Describe the request

Title: Glass (Agents layout): preview HTML files on open — parity with “Open in Browser”

Summary

In the classic file explorer, I can right-click an .html file and use Open in Browser to see a rendered preview in Cursor’s built-in browser. In Glass (Agents layout), selecting the same file in the Files tab opens the source in the editor panel instead. The preview path exists; it just isn’t wired into Glass’s default file-open flow.

Current behavior

Classic explorer: Right-click .html → Open in Browser → rendered preview :white_check_mark:
Glass Files tab (⌘G): Click/select .html → source code only :cross_mark:
Preview is only available via workarounds (context menu in classic explorer, Live Preview extension, manual Browser tab + URL, keybindings)
Expected behavior

When I select or open an .html file in Glass, I should get a rendered preview by default (or via a single obvious action), consistent with explorer’s Open in Browser:

Preferred: Open in the Browser tab (⇧⌘B) automatically, or split source + preview.
Minimum: Same Open in Browser action in Glass’s file tree context menu, and/or Enter on a selected .html file opens preview (not only source).
Optional setting: “Open HTML in browser by default in Glass” vs “Open as source” (similar to markdown preview vs raw).
Why it matters

Many projects (marketing sites, design prototypes, static HTML) are edited by viewing more than by reading markup. Glass is the primary workflow for agent-assisted work; forcing a separate explorer or manual browser step breaks that flow.

Context

Command already exists: filesExplorer.openFileInBrowser → workbench.action.openBrowserEditor
Glass file open path: glass.openFileInStableTab (source editor)
Request is UX parity, not new infrastructure
Environment

Cursor Agents / Glass layout
macOS (adjust if needed)
Workspace with static HTML under e.g. prototypes/*.html

Hey @Francis_Quintal_Lauz!

Thanks for flagging. This is something we want to add! Still working through the right UX.
