Actually, on the subject of this;
This is probably something that would be a major pain to implement, but perhaps a sorting option?
So like, you can search all the kits on the site for certain things. Such as humbuckers, set neck, floyd, etc.
Was just thinking then it'd be handy to be able to search for bolt on necks, to make it easier. Purely me being too lazy to scour through, but would be a handy feature for a few things/ bringing all the items you want right under your nose
