Hi! I agree with martin - such a Modeler could be a great improvement but I assumed it would be somethink like the WxGUI_Modeler .. (Also ESRI has something like that) Putting things(modules) together like a diagram would be much easier for the user than remembering a chain .. Did not Tim start something like that with Openmodeler? (http://openmodeller.sourceforge.net/) Do you think we could use that?
