So, got an illustration that is utterly meaningless and totally incomprehensible... DELETE.
Nope... That's not going to fly with the client...
So, after finally figuring out what the illustration is supposed to mean, I set out to redo it from scratch because the current one is completely without value.
3 hours later... Done. And it's understandable.
Problem is that the issue should be transparent to the developer using the tool.
Sigh...
Cheers, because I really need a beer after that one!
