Settings reference

Open Crest → Settings on Mac. On iPhone and iPad, open Settings from the browser interface. Some controls appear only on the platform that supports them.

General

Choose startup, window, appearance, and update behavior. On direct Mac builds, this is also where you choose the Stable or Nightly update channel when offered.

Quick Window and Peek

Choose what happens to links from other apps, which Space supplies their signed-in session, how long Quick Windows remain recoverable, and whether eligible links from pinned or saved pages open in Peek. Link Routing rules live here too.

Shortcuts

Search the complete Mac command catalog, record a replacement, inspect conflicts, clear an assignment, or restore the default. Extension commands are shown separately because they belong to the extension installed in that Space.

Spaces

Create, rename, reorder, customize, or remove Spaces. Each Space owns its own browsing profile and can use its own cleanup and data-retention choices.

Sync

Enable or disable iCloud sync and review its current state. Private Spaces and transient browsing are intentionally excluded.

Privacy

Control browsing-data retention, content blocking, site permissions, private browsing behavior, and other privacy boundaries.

Passwords

Review Crest Passwords by Space, authenticate to reveal or export sensitive credentials, and choose whether eligible credentials participate in iCloud Keychain sync.

Extensions

Available on Mac. Install, enable, remove, pin, inspect, update, and control site access for extensions in the current Space.

Advanced

Import and export browser data, access runtime and diagnostic controls, and manage developer-facing behavior. Change advanced options deliberately; many of them exist to diagnose a specific browser or WebKit condition rather than improve everyday browsing.
