Near the top of the left side corner of most Element Detail pages is the Actions drop-down menu. Here you can select to Export the element details as a report.
You can also add the element to a collection by selecting Add to Collection.

And, you can Add/Edit Labels which is like adding tags that can help you keep track of items you'd like to revisit.

To do this, click on Add/Edit Labels and assign it a unique label name, then press Save. To view this item again in the future, all you need to do is type in the label in the search box.
