EDIT - Does not synchronize tabs between workspaces opened in different computers. This renders it completely useless.

It works as you’d expect. The interface is clear, easy to understand and user-friendly. Windows are renamed to match the workspace name, although this takes a little while to happen when reopened. The workspace name also appears on the extension icon, so it’s best to keep it short.

It would be nice if it supported syncing via a cloud service (in my case, Dropbox) because storage.sync only supports 100 KB of data per file, and I get the feeling that won't be enough.
