Functionality Enhancements.

[Bollebib]

1)I wish Youtube center didn't load tabs into the player if the option "don't load tabs until selected" is active.
Marking them to not play in the beginning is different as it makes firefox slower to load,potentially. But also because you either need to force them to not play, and loose playlist functionality, or just leave that off (and if you have multiple youtube tabs open they will all play at once on load)

It also will unclutter the youtube center playlist.

2. there should also perhaps be a setting to only stop loading the first video of a playlist. If you start a playlist after that it should let the playlist complete

3. An option to not have history at all,not even in the current session. I only would like video's that are currently in the player.

4. keyboard shortcut (customizable?) to play/pause the last active video.

Other then these small nibbles I have I quite like Youtube control center. It needs just a few more settings to make it easier to interact with and to respect some settings the user has made. Great work!
