Hey,
after editing a graph with yEd, I would love the option to "refresh" all exports of that graph. This would imply storing a relative path, the export format and settings for each export made from a .graphml file.
Otherwise, keep up the good work! ![yes yes](http://yed.yworks.com/support/qa/qa-plugin/wysiwyg-editor/plugins/smiley/images/thumbs_up.gif)
