Media Preview & Smarter Badges

New

  • Open PDFs, Videos & Audio In The Built-In Browser: Click a PDF, video, or audio file in the file explorer — and it opens directly in the browser panel — no need to switch to an external app

  • Open PDFs, Videos & Audio In The Built-In Browser: Supported formats — PDF, MP4, WebM, OGV for video; MP3, WAV, OGG, FLAC, AAC, M4A, OPUS for audio

  • Open PDFs, Videos & Audio In The Built-In Browser: Placeholder card in the editor — if you open a media file via the editor tabs, a styled card explains the file type and offers an "Open in Browser" button

  • Open PDFs, Videos & Audio In The Built-In Browser: Falls back to editor tab — if the browser tab limit is reached

Improved

  • MCP tool badges now appear on the correct terminal — each badge is tied to the AI agent that triggered the tool call, not just the most recently active terminal Tools carry a terminal identity through the MCP bridge so badges land on the right terminal even with multiple agents running simultaneously Sub-agent detection expanded to recognize Codex inline-mode output patterns (Running , Ran ) alongside the existing Claude Bash() format

  • Browser panel waits for webview to initialize — before loading a URL — fixes blank pages when opening browser tabs rapidly

Fixed

  • Fixed duplicate file explorer panels in Terminal Center + Chat layout — the left sidebar no longer renders a second file tree when the preset already places it in the right sidebar

  • Fixed editor collapse button showing in Terminal Center and Terminal Right layouts — since the editor lives inside the right sidebar in those layouts, the toggle button is now hidden

  • Fixed right sidebar close button and shortcut closing the editor in Terminal Center layout — the close action is blocked when the editor panel lives in the right sidebar

  • Fixed browser not loading file:// URLs — local file paths are now recognized and no longer prefixed with http://

  • Fixed PDF rendering in browser — enabled the Chromium PDF plugin via plugins=yes webpreference

  • Video and audio player embedded in the 1DevTool browser panel playing a media file
