Extensions
Switch off the parts of the workspace you do not use — Browser panel, HTTP client, Database client, Mobile emulator, ToolBox, AI Diff and Repo. Turning one off removes its panels from every layout and stops its tools reaching your agents and your phone; turning it back on restores your arrangement exactly.
Why You Need This
How this feature boosts your daily productivity
A workspace that does seven things should not charge you for the six you never open. Settings → Extensions is one switch per feature, and it is a real gate rather than a cosmetic one: the panels leave every layout, the MCP tools stop executing, and the phone's tool namespaces answer "feature disabled" instead of half-working. The important half is that it is reversible without cost — saved layouts are never rewritten for a disabled extension, they are filtered at read time, so switching one back on puts every panel where it was with its connections, saved requests and browser tabs intact. Right-click any right-sidebar tab strip for the same switches without opening Settings. New installs now start lean with just the browser, and the SQL Server driver downloads on first use (3.5 MB) against a signature built into the app rather than shipping inside it.
How It Works
Get started in 4 simple steps
Open Settings → Extensions
One switch each for Browser panel, HTTP client, Database client, Mobile emulator, ToolBox, AI Diff and Repo.
Switch off what you do not use
The panels leave every layout, the feature's MCP tools stop executing for your agents, and the phone's tool namespaces answer that the feature is disabled.
Switch it back on and get your layout
Saved layouts are never rewritten — they are filtered at read time — so every panel returns where it was, with its connections, saved requests and browser tabs intact.
Or use the right-click menu
Right-click any right-sidebar tab strip for the same switches plus Extension settings…, without opening Settings at all.
