I notice that the list of builds quickly becomes just a long list of ships and organising it becomes somewhat impossible. Also with having other peoples ships in that list it will become a bit chaotic. So having a way to make directories to sort out the list. Sometimes a non functional blue print can fill up the list and some ships are just fun the keep around as a part of keep sake.
Would be nice to be able to organize the ships, make a list of your combat ships to separate experimental/decorative/counter ship that are rarely or never used.
Can also just cleanse your lists every now and than, usually don't have much need for more than 30ish designs for combat.
