I don't think that a request section is really interesting. If a blueprint is desired, a search is started directly and that happens very rarely.
Actually everything has been offered so far, only it's hard to find.
Naming the blueprints like "my very first beautiful house" or my "first project" or whatever says very little about whether it is a modern or medieval building.
The search function cannot help in these cases, but finds nothing at all.
This confusion will probably stay that way, because everyone wants to specialize with his title.
I would also offer these blueprints in steam and finally to sort them by category.
But who should do that?
