Create a Cave
A Cave is a top-level space for organizing bookmarks. Use one for work, hobbies, entertainment, study, or any other part of your life that you want to keep separate.
In the left sidebar, select Hammer Out a Cave to create a new Cave.
Add Chests for related bookmarks
Each Cave can contain unlimited Chests and bookmarks. A Chest works like a folder, so you can create one for a project, topic, or group of sites.
Make it your default when it is useful
You can set a Cave as the default one shown in a new tab by selecting the star button in the Cave toolbar. This setting is local, so different browsers and devices can open different default Caves.
