Great UI design; clean, intuitive, and useful. Thank you for this!
On a side note, I'd really like to know what broken mechanism aggressively downranks such quality community submissions. 67 upvotes in 2 hours, and only ranked 9th. Meanwhile, another post with fewer upvotes in more time is ranked 2nd. Something is very wrong here. I'd love to see more posts like this one, and fewer standard blog articles that are hitting the front page for the third time in five years.
