This iswas a site that fixed a lot of the shortcomings of the website ultimate-guitar.com by scraping in real time any tab that you requested and rendered it in a more efficient and less intrusive manner.
Sadly it has been shut down, because ultimate-guitar don't like any fun. It not only rendered the site in a better manner, a quicker manner, but it also added features to the site that I as a guitar player always wanted
Easily find your liked songs on the home page
You could pin rows of tabs to be sticky while you play along
Make playlists to play through a set with your buds
I mirrored the url structure to the site, so I got to finally do a project with the URL hijacking method - any ultimate-guitar.com tab could be changed to ultimate-guitarx.com (the addition of the x) and it would render with my site instead.
It was fun to work with more complex regex than I ever had before, to convert their plain text tabbing into rich interactive works.
