I'm a hobbyist and not on the dev team for Opera (nor even remotely related) but it appears as if you want some user replies. If you're interested, still, and you're looking from a reply from someone who was tangentially related to the software business (my degree is in applied mathematics and my business is now sold but was both vehicular and traffic modeling) then I'd be willing to spare a few minutes for your project.
My real name is available via email and such should be conducted there to maintain a modicum of privacy. I can be reached at uninvolved (at) outlook (dot) com if you'd like (change the obvious to the obvious). Put "Opera" in the subject or I may not notice. 'Tis up to you. I'm fairly verbose and have an adequate vocabulary so you can get BS points that way too.
