Angst with Orders & Mod Questions

In the 'orders' screen, I can't find the 'clear orders' button. Where is it?

Also, for most games, there are nice fan made drag-and-drop enviornments, or something else thats idiot proof. As an idiot, I'd like some guidence as to where I'd find something like this. The only thing I really want is to be able to make the quadrent.
