I am looking for some kind of a workflow editor for WF, has anyone seen anything like this?
I would like to be able to edit XML files, but then have those XML files be opened by my app.
Maybe a different approach is ok too!

One way would be to rehost the WF4 designer in your app, similar to the one that is available in Visual Studio. Its also possible to host it on Internet Explorer as an XBAP application.
As for manipulating the XAML XML file(s) containing your workflow structure, the easiest way would be to create your activities via code and serialize them down (and up) using the ActivityXamlServices
type. See here for more info on this.
