I have an idea, that maybe there can be a way to have "classes" of sorts, kind of like in RoR, for the vehicle selector. You might also be able to put the vehicles in those class folders yourself, so that if the author doesn't tell you, maybe in the thread, where it should go, you can do it yourself. It would help some people (like me XD) who have big vehicle selector lists and would like to shorten it down to certain categories, rather than shuffling through the list.
This is a very good idea ! Plus, it should be possible to add vehicle informations in a jbeam file and filter the list by... brand (for example). No ?
I'd be happy with Brands and Mods sections. So official cars go in their brands and mods obviously go in mods.
