• Fix the generation of dot files to handle strings with quotes in them properly (I found these in some of the qudt.org files). I may not have fixed all cases where they could appear. but the main ones.
• Adjust the splitter/editor layout so the scrollbar is just on the editor and doesn’t affect the diagram pane
• Put some of the form elements in a table to make the layout a little more stable – but maybe this is just my taste
