Change the HD button to HQ Back when HD was rolled out to YouTube it was actually labeled under the button "HQ". This would mean the "HD" button would be incorrect, and I feel that should be changed.

Unlisted/private videos Would be great to have them.
Besides being useful for showing videos to certain people only, I could also use it to "hold back" a video before it's ready to be published (making changes to the video metadata and such, especially right now where it publishes as soon as I upload it)
Also in case I want to bring a video back in the future and not delete it completely

Languages and mobile It would be good to add language versions and mobile apps.
