Persistent browsing contexts.

Modern browsers treat your browsing as ephemeral. Close the window and most of the shape of your work is gone, scroll positions, the page you read three times, the trail you were following. Spaces flip that assumption. Each Space is a persistent context that survives close, restart, and crash. Open the browser tomorrow and your Research Space is exactly where you left it.

A Space holds tabs, groups, the active split layout, scroll positions per tab, annotations, and the navigation trail. State is written to a local SQLite database on every meaningful change. Switching Spaces is instant: the previous Space stays alive in memory, the new one swaps in. Closing the browser flushes everything to disk. Reopening reads it back.

Use Spaces to separate the contexts you naturally have: Work, Personal, a long-running research project, a shopping comparison, travel planning. The first Space is created automatically. Add more from the sidebar with a single click. There's no limit. Spaces you haven't touched in a while stay on disk and don't consume memory.
