terminal control via MCP tools.

What's new in 4.10.0

Added

• See when an agent is driving a browser tab, and stop it. A browser tab
now shows a mark in its toolbar and on its tab while an agent is acting on
it. Stop ends the agent's current action and pauses it on that tab until
you resume; Take over hands the tab to you until you hand it back. Tabs of
your own Chrome that you lent to an agent can be returned from the
workspace's Chrome profile menu with Return to me. Before, the only sign
was the help bar, and there was no way to stop or take back a tab.

  • Office shows every workspace at once. The Office plugin (by @bluemas) now seats every local workspace's agents in one office, so everyone who needs you queues at the same boss desk. Clicking an employee takes you to that workspace's pane. The office is scaled to fit the page, so it never scrolls. This needs a new plugin permission, agent.state.read.all, which the approval prompt lists on its own line; without it, Office shows only the current workspace, as before. An installed Office updates itself and asks for approval again (#2613).
  • Plugins shows what each catalog plugin looks like. The detail for Office and Agent status now has a real screenshot of that plugin's page, between the credit line and the description. Before, you only saw a description until you installed and opened the plugin. A bundle you installed by hand shows no preview (#2618).

• Run now can end a finished run's leftover session and start. A finished
schedule run keeps its agent session open for up to 10 minutes, and until
now a Run now in that window was only refused with "Not started:previous
run's session still open", so you had to wait. Now the schedule offers to
end that session and start:an inline confirm names the session, Cancel is
focused, and confirming ends only that one session before the run starts. A
run that is still going never gets the offer, and scheduled runs are
unchanged. (#2625)

  • Bots in a group chat can react instead of replying, and a bot that stays quiet still shows it saw the message. In a group chat, a bot woken by your message, or by another bot mentioning it, can answer with a single emoji. The emoji appears under that message as a small chip, the way a messenger shows a reaction. A bot that has nothing to add leaves a quiet acknowledgement there (👍, 👀, ✅ or 🙌, always the same one for that bot and message). Hover over a chip to see who reacted or who saw it. …
