September 2017: Updated for new layout.
Adds an extension button that expands YouTube videos to the full window and activates HD quality (optional, see options page).
The functionality can also be activated with a keyboard shortcut (see options page).
The extension is efficient, does not require unnecessary permissions and works directly on YouTube with minimal changes (so no surprises!).
