Major 0.16.x Additions

🪄 Maestro Cue is a new trigger-based cross-agent orchestration capability that lets heartbeats, GitHub issues/PRs, file system monitors, and other data sources bring your agents to life and pass work between one another.

💻 Full-featured xterm.js terminal tabs sit alongside your AI and file preview tabs, with support for opening and renaming multiple terminals.

🧑‍✈️ GitHub Copilot-CLI joins Maestro as a first-class agent with end-to-end integration for both local and remote (over SSH) execution.

🌐 The web/mobile interface gained real PTY terminals, swipeable panels, notification dropdowns, and dozens of desktop-equivalent features for a full touch-friendly experience on tablets and phones.

🔗 SSH Shared History synchronizes Maestro instances working on the same project, with each host writing per-hostname JSONL files to .maestro/history/ on the remote so participants see each other's work.

🌍 Browser tabs open web pages directly inside Maestro as first-class tabs with a full address bar, navigation controls, session persistence across restarts, and bulk close support.

Changes in v0.16.19-RC

✨ New

🎨 Olive Nights theme joins the palette.
📊 Usage & Stats: a Usage Dashboard tracks Claude and Codex token consumption over time with p50-p99 duration percentiles (shared distribution card, also on Cue run stats), plus read-only maestro-cli stats and maestro-cli stats-query for metrics and arbitrary SQL from the terminal.
🌐 Browser tabs: an in-page Cmd+F find bar with match counter and next/previous, Cmd+L to focus the address bar, Cmd+←/→ for back/forward, a keep-alive policy (off / recent / all, with a configurable limit) that keeps background tabs mounted, and renaming with sticky custom titles plus a Reset Name action.
🖼️ Image editing: edit images in place in a file-preview tab and save back to disk, a one-click color preset popover in the annotator, and an "Edit Image from Clipboard" command-palette action.
🚦 Auto Run playbooks support human-in-the-loop gate markers that pause the run until you approve.
🩺 Agents probe their own capabilities on launch and persist a status snapshot, with a dedicated Settings → Agents tab and a Re-probe button.
➗ Chat surfaces render $$...$$ display math and inline math via KaTeX.
📁 A "New Folder" action in the File Explorer context menu creates folders right where you need them, locally or over SSH.
📥 Drag files from Finder/Explorer into the chat to attach them or insert multiple @path mentions, with scoped drop zones and "Drop to move to root" / "Drop to import" overlays.
😴 The quit-confirmation modal gains a "Quit when idle" option that waits for thinking agents, Auto Run, terminal tasks, Cue runs, and group chats to finish, with a status pill while it waits.
⭐ Bookmarked agents get their own Bookmarks section in the web/mobile side panel.

🔧 Improved

🗂️ The Cue pipeline canvas gained an Auto-arrange button that tidies nodes into flow-depth columns (single pipeline) or a balanced grid (All Pipelines), packing independent chains into horizontal bands with orthogonal step edges.
📐 The Cue pipeline canvas supports Shift+drag panning in any interaction mode, with mouse/keyboard reference tables in the Cue Help modal.
⏸️ Queued AI messages can be individually held and resumed, and an all-held queue is treated as drained.
🧮 Auto Run's fresh-context recommendation scales by task count and context window (5/10/20 tasks at 256K/512K/1M) and warns when your manual pick disagrees.
🌲 Auto Run can launch into a different worktree even while the current agent is still working.
⌨️ Shift+Arrow in the Files pane extends a Finder-style range selection.
🔀 Cmd+Shift+2 now launches Auto Run, with the expanded preview moving to Cmd+Shift+E.
🧭 Breadcrumb back/forward restores any tab kind (AI, file preview, browser, or terminal), not just AI tabs.
🗺️ The Document Graph gained a click/drag minimap and Shift+scroll panning, and switching agents now closes the full-screen graph so it can't swallow clicks on the agent you jumped to.
💡 Agents are nudged to embed screenshots, charts, and diagrams inline so they render directly in the chat.
