Hello, after the current change has been finally reviewed I will change the plugin to use only one document and one editor with a combo box in the top toolbar to switch between open diagrams. This change will reduce the complexity of the source code but I have to add some features which will get lost, e.g. a short cut to cycle throw diagrams.
