Allow users to view videos in HD It would be nice if users could watch videos in 1080p. Another idea I have is to let normal users watch up to 720p and partners could watch videos up to at least 1080p. I mean like it's 2018 and I think that would be a smart choice even though this website is capturing the classic YouTube vibe. I would get it if you can't do that for financial reasons but it would be pretty neat to see.

ANNOTATIONS and THUMBNAILS Youtube recently removed annotations, so it would be a fun stab at them to enable them for vidlii. Also, the ability to add thumbnails for all users, not just partners. Other than that, GREAT SITE!! I appreciate the effort you guys have taken to create a cool portal back to internet video sites of 2005!
