Message:
amused-web: make the filtering work Generate the HTML for the filter input in js (it's useless to have it there otherwise) and actually filter the entries. It's a basic case insensitive match, but it's a start. To do so, add dispatch event type X: to mark the end of the playlist so js can replay the filtering.
