Great, love to hear that, and I understand the itoo philosophy where usability comes first.
I'm sure I have still some interesting suggestions, but I'll think about them first cause now they're just some idea's here and there.
However one of them is an integrated slicing option within the rc tool like the separate script you provided.
If your goal is simplicity and speed it would be a game changer if you could model your window for ex... then opening the rc tool, clicking the object you'd want (setting the dimensions on the elements), and then the individual segments are automatically added in the rc wire diagram.
Does that sound logic? :p
I just noticed that I'm repeating this process quite often, and that could speed up the process
