Nick & Otto,
I agree with your requests. Simply a question of time as usual.
I already have the bit of code to display diagrams, but most of the work
is with the graphics editor.
Fons is currently polishing a new superb user interface with the Windows95
look and feel (to be announced soon). I am waiting the integration in Root
to redesign the graphics editor interface
