-#### How it Works
+### How it Works
+When the DOM is mutated, FreshView polls the DOM for HTML elements that match the expected structure of a YouTube™ video.  Each HTML element that matches the structure of a YouTube™ video is converted into a `Video` object.  All Videos with a view progress that meets or exceeds the current view threshold are added to a dynamic collection of Videos known as an `Album`.  When a Video is added to an Album, it is displayed or hidden depending on the state of the *Hide Videos* toggle.  Similarly, when a Video is removed from an Album, it is reverted to a visible state.

-##### Technical Notes
+#### Technical Notes
 1. The visibility of a Video is controlled by setting the `display` attribute of a YouTube™ video element's `style`.
 1. The view progress of a Video is derived from the red bar shown along the bottom of a YouTube™ video element.
 1. Only DOM `childList` mutations trigger a poll request.
 1. DOM mutations that occur within 200 milliseconds of one another are batched into a single poll request.
-1. The view threshold slider is only synced on `mouseup` events to avoid exceeding the `storage.sync` quota.
-1. YouTube™ videos that appear in the Autoplay panel or the History tab are ignored.
+1. YouTube™ videos that appear in the Autoplay panel are ignored.
+1. A YouTube™ page is identified by the concatenation of its path and query arguments.
+1. The durations of the CSS transitions are initialized *after* the first animation frame to enable instantaneous loading.
