Like I already replied, regarding any 3rd party integration we may suggest, it starts with $80... I think it's a top notch price. Guys from SMF or phpBB would probably require for a customized integration 10x times bigger price (the other question is, they are already "sponsored" by their private investors, but the only investor in miniBB is me and the customers who pay for my work).
We suggest such price because with miniBB it's all is simple... but still, it requires some time. I suppose you may imagine my time is very costly. Each working hour rates high, so afterall, I am suggesting to publish all codes for public with giving all credits to your project or website, so this is the best offer I could have regarding PTC integration or any other else. Sorry, I can't work for free for private goals in the capitalism world.
As about the "graphical" implementation of editing the core settings... thanks, I already have this add-on in mind long time ago; unfortunately, family issues still force me to work on the customized tasks more than developing this... let's hope after I get my hands free at some point (it's coming even closer this year), this task should be the first I develop... thanks for your "+1" on this.
