Its a great tool.

One feature I missed in earlier versions was the ability to define styles (like line styles) and select the style before drawing an element, rather than draw an element then setting its style afterwards. If that was possible I could select a line style and draw like any number of elements of that style, instead of going to each drawn element and changing its style. Is it possible to use that workflow in present versions?

Another nice feature would have been to have an integrated library of shapes, to use in your own diagrams.
