About bookmarks

Bookmarks allow you to save a given navigation and component state so you can return to it at a later time or email it to other users.

Note:

A bookmark is only guaranteed to work if the page that it points to has not been changed. If components have been added, removed, or modified, then the bookmark may no longer be valid.

You delete bookmarks manually, or in the following situations:

When a page or project is removed, any bookmarks for that page or project are also removed.
When a user is removed, any bookmarks created by that user are also removed.
