Sub-Agent Badge and History Viewer
When an AI CLI spawns a nested sub-agent (a Claude Bash sub-agent, a tool-call agent), a small badge appears on the terminal showing which CLI is running underneath and how long it's been alive. Click the badge to open a live-tail viewer of the sub-agent's session log.

Why You Need This
How this feature boosts your daily productivity
Modern AI CLIs spawn sub-agents constantly — Claude fires off bash sub-agents, tool-call agents, summarizer passes — and you had no way to see what they were doing without opening their log files by hand. The sub-agent badge surfaces the nested agent live, and one click opens a color-coded viewer that live-tails its session.
How It Works
Get started in 4 simple steps
Open a Terminal
Click "+" to create a new terminal tab. Choose from Claude Code, Codex, Gemini CLI, Amp, bash, zsh, or custom shells.
Arrange Your Layout
Switch between grid, columns, or fullscreen with one click. Drag dividers to resize panes to your preference.
Run Your Agents
Start your AI agents with pre-configured prompts or type freely. Watch them work in real-time with status indicators.
Monitor & Manage
Use the Terminal Dashboard for a bird's-eye view. Sessions persist across restarts so you never lose context.

Why It Matters
The productivity impact of having terminal & ai agents built into your workspace
Zero Context Switching
All your AI agents and terminals live in one window. No more alt-tabbing between 5 different terminal apps.
Visual Status Tracking
Color-coded tabs and the Kanban dashboard tell you which agents are done, running, or need attention — at a glance.
Persistent Sessions
Tmux-backed persistence means your terminal state survives crashes and restarts. Never lose scrollback history again.
Flexible Arrangements
One-click layouts adapt to your task: grid for monitoring, columns for comparing, fullscreen for deep focus.
