What is the content collector tool used for?

For something like this:

If you have content which has multiple uses in the same or in other documents you can collect it, also several in a raw. Then you find it in the convoyer panel and you can drop the collected contens onnce or multiple times on other places in the same or in other documents. You can link other instances to the first original content. If those are linked, changes in the first original item are reflected in all linked instances. You might click in link panel to update the instances. Changes must be done in the original object.
