Spaces 作者： Thovthe

Spaces keeps track of new tabs opened in each workspace and also tabs that you close. It also allows you to quickly move a tab that you are currently viewing into any other space whether it's open or closed. Great for when you find yourself opening a tab out of context with what you are currently working on and want to come back to it later.

Find you have 50+ tabs open? Do you abuse "Bookmark tabs..." for session management?

Spaces was developed to help users that tend to keep way too many tabs open. It encourages you to move tabs that are not immediately relevant into a different, more appropriate space - thus removing it from your current window. This keeps your browsing session manageable - both visually and from a memory perspective.

Isn't this essentially just bookmarks with folders? Yeah, pretty much - but you'll want to use it.
