I wanted a tool that would analyze a complete web site, and report what CSS selectors and IDs are dead. By dead, I mean one of two things — either the ID or selector is referenced from the HTML and undefined in the CSS or it is defined in the CSS but never referenced in the HTML.
When I want to learn a new song on guitar, I often search for chords online. There are many sites that provide chords and tabs, and Google indexes them nicely. But the quality of chords is often poor, and there’s no way to submit corrections. When I ran a MoinMoin wiki, I kept my fixed versions of songs there. Even making modifications to existing chords was painful though, since it involved hand-editing a plain text file and ensuring that the chords were properly aligned with the lyrics. My preferred solution to this problem is to write a web application to facilitate easy collaborative editing of simple folk/rock/pop songs.
