Nice and simple! The design is awesome besides the copyright, help and private policy links. Would look 10x better if they would hover just above the bottom end. Breaks the beautiful white space.

EDIT: That would be awesome, thank you! :)
By the way, I noticed bookmarks without https:// in front of the link won't work (for example 'www.google.com' or 'google.com' won't work). Took me some time to figure it out so maybe you want to mention this in the description or maybe let a little warning show when you try to save a bookmark that doesn't start with https://
