Two New Layouts, and Deliveries You Can Trust
Classic puts the File Explorer back on its own — a standalone file tree beside a dedicated Editor, and the Editor drops its embedded tree wherever you place the explorer
Swarms That Refuse Up Front
A Swarm that cannot run is refused up front, with the reason — and the message names the agents that can run sandboxed workers: Codex, Claude and Cursor
Proven Sends, Markdown Notes & Agent Batches
Sticky notes render Markdown — a note you are not editing shows as formatted text, and the MD button switches between writing and reading

View allYour sidebar was doing two jobs. Now it only does one.
Horizon moves your projects to a strip of icons across the top of the window, so the file tree gets the whole left sidebar. Classic brings back a standalone File Explorer beside a dedicated Editor. And any layout you can see can be pushed to every project in one click.
Proof your prompt actually reached the agent
A prompt is now reported as sent only after 1DevTool confirms it left the agent's composer — so a delegation can no longer look live while the agent sits idle. Plus Markdown sticky notes, per-agent terminal counts, and a file tree you can resize or collapse.
Browse and edit in one workspace
The File Tree and the editor now share a single workspace tab that keeps your expanded folders, open files and scroll position while you work elsewhere — plus Mission Control that reveals itself when work starts, one-click project actions, and a local password generator.
