Facebook is always testing new features. Sometimes they eventually roll out to everyone. Sometimes they don't. In the case of both of these features, users would only stand to benefit.
The first, and arguably more helpful of the two, is a "View Insights" button, which has been appearing on posts for some Page administrators. This essentially lets you quickly and easily see insights for specific posts, such as people reached, comparison to average, and post clicks.
The second feature in testing is a button that appears on videos allowing the user to "Watch later". It has an icon that matches Facebook's save feature, which the company has recently been reminding people to use. It reportedly appears in your saved items when you click it.
TechCrunch, which shares a screenshot of that one, says it has confirmed with Facebook that the company is testing this on the desktop.

The watch later feature on YouTube is an invaluable part of the YouTube experience, so this would be a major feature addition in terms of bringing Facebook's video offerings up to par with that.
Facebook recently launched a feature for Page admins that kind of relates to both of these new features. It added a videos tab to Page Insights (pictured at the top).
