Just finished (mostly) the recipe popup. Unlike the others that displays a box on hover the recipe popups are implemented as a combination tree. So you hit the [button]+[/buton] sign beside a recipe and it will expand showing detailed information including a list of components. If the components can be tradeskilled they too will have a [button]+[/buton] sign beside them. Try it out here with the cured silk recipes:
