From e2762ad04c6bc8eddadcd95bc2640611cdd763fc Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 27 Oct 2026 21:13:36 +0000 Subject: [PATCH 1/4] Seven new extensions: browser, media, projects, timers, ports, network, AI - Browser: history and bookmarks of Firefox and Chromium browsers, favicons, Firefox tabs. - Media Controls: now playing and controls for any MPRIS player, over busctl. - Code Projects: recent projects of VS Code, Cursor, Zed, JetBrains and git folders. - Timers: systemd timers that ring with a notification even when Backslash is closed. - Ports: listening ports with their process and project; open or stop them. - Network & Devices: Wi-Fi, Bluetooth, audio outputs, VPNs and Tailscale. - AI: ask questions and work on copied text with Claude, OpenAI, Mistral, Groq, OpenRouter or Ollama, streaming the answer. Each has its parsing in lib.ts with tests; CI runs them.
