Hello all. Great to see folks using the graphical editor. My replies to some of the comments follow:
@dr_pompeii: To use the Spring Integration graph, I would highly recommend going to STS 2.5. The reason you don't see the graph in STS 2.3.2, and why there's no documentation for the STS.ini flag, is because the graph in that build was a work in progress.
@racumin: The Integration graph does support printing & exporting. To print the graph you must be on the integration-graph tab. If you try to print from any other tab of the editor, you will print the XML instead. Saving the graph as an image works the same way, but you need to select the "Export..." command from the File menu. We support exporting to JPEG, PNG, and BMP
@GPS: I've just tried to edit your sample.xml file and you're right, it does take a long time make edits (though I do make it pass the pinwheeling). I haven't worked with a file as large as the one you posted, so I'll see what I can do about optimizing the editor.
