Terminal Manager & Diagram Export: Control Every AI Agent From One Dashboard

Running six AI terminals across three projects? The Terminal Manager gives you a Kanban board of every terminal across every project — plus one-click Mermaid diagram export to PNG, JPEG, and SVG.

Terminal Manager & Diagram Export: Control Every AI Agent From One Dashboard

You're running Claude Code on the backend, Codex on the frontend, a Bash terminal compiling assets, and Gemini CLI writing docs. That's four terminals in one project. Multiply by three projects and you have twelve terminals scattered across your workspace. Which ones are still running? Which finished five minutes ago? Which one threw an error you haven't noticed yet?

Without a centralized view, your AI coding workflow becomes a guessing game. You Alt-Tab between terminals, scroll through output hoping to spot the one that needs attention, and waste time on terminals that are already idle.

1DevTool v1.9.3 introduces the Terminal Manager — a unified dashboard to view, search, and control every terminal across all your projects — plus Diagram Export to save Mermaid diagrams as PNG, JPEG, or SVG.

Why You Need a Terminal Manager

Modern AI code editors encourage running multiple agents simultaneously. You kick off Claude Code for a refactor, Codex for tests, and Gemini CLI for documentation — all in parallel. The problem isn't running them. The problem is knowing what they're doing.

Traditional terminal setups give you tabs or panes. That works for two or three terminals. But agentic coding workflows routinely hit six, eight, or twelve terminals across multiple projects. Tabs don't scale. You need a bird's-eye view.

How the Terminal Manager Works

The Terminal Manager is a full-screen overlay that shows every terminal across every project in a single, searchable view. It's organized as a Kanban board with three columns: Idle, Running, and Needs Review.

Kanban Board: See Everything at a Glance

Each terminal appears as a card with the project name (color-coded), terminal name, agent type, and a live status indicator. The three columns tell you instantly:

  • Idle (gray dot) — terminals waiting for input or finished
  • Running (green dot) — AI agents actively processing
  • Needs Review (amber dot) — agents that finished and generated output worth reviewing

Click any card to jump directly to that terminal in its project. The dashboard polls every 10 seconds to keep statuses fresh, and you can navigate entirely with arrow keys and Enter.

Live Preview Pane

Click a terminal card to see its recent output in a preview pane — without leaving the manager. This lets you quickly triage which terminals need attention. If the preview shows the agent is still mid-task, you move on. If it shows an error or a completion message, you click through to the full terminal.

Type in the search bar to filter terminals by name, project, agent type, or even buffer content. Looking for the terminal where Claude Code mentioned a migration file? Search for "migration" and the manager filters to matching terminals instantly.

Bulk Actions: Close, Send Commands, Create

The Terminal Manager isn't just for viewing — it's for controlling:

  • Bulk close: Select multiple terminals with checkboxes, or use "close idle" to clean up all inactive terminals in a project with one click
  • Quick actions: Send Ctrl+C, Ctrl+D, or Clear to any terminal directly from its card — no need to switch to the terminal first
  • Create terminals: Launch new Bash, Claude Code, Codex, or Gemini CLI terminals in any project without leaving the manager

Diagram Export: Mermaid to PNG, JPEG, SVG

AI agents frequently generate Mermaid diagrams — architecture diagrams, sequence diagrams, flowcharts. 1DevTool already renders these inline in the markdown editor. Now you can export any diagram as a high-resolution image.

  • PNG — for docs, Slack, and presentations (2x Retina resolution by default)
  • JPEG — for smaller file sizes when transparency isn't needed
  • SVG — for scalable graphics in web pages and design tools

Click any rendered diagram in the editor and select your export format from the menu. The 2x Retina support means exported images look crisp on high-DPI displays without any extra configuration.

Under the Hood: Faster and Lighter

v1.9.3 also includes significant performance improvements that make the entire app snappier:

  • Smarter terminal resource management — inactive terminals release rendering resources and auto-detach background tmux sessions, reducing memory usage
  • Faster git status — refreshes only when files actually change instead of polling every 10 seconds
  • Faster file change detection — instant refresh from file system events instead of polling every 2 seconds
  • No more file watcher leaks — watchers are properly cleaned up when switching between projects
