I have sorted my runtimes in such way that they fit with my peronal working flow. And I allways try to find logical way to splitt  my runtime even more. Right now I'm working on my "Plants" runtime  -going to splitt it into; Trees, bushes, flowers and fungi . . I think :P not really sure yet. And I also want to splitt my Architecture runtime, since it contains all sort of buildings, temples, homes and just building parts; i dont like that runtime its too big. But I also have a little issue of overthink things; some items I cant fit - some items is very hard to place, is it a temple? is it a structure?...hmm well it aint a home, but where do I place it? :P

Some of my newest runtime is "Jewelry" - wich is all jewelry items, "Weapons" - wich is all kind of weapons, no matter wich figure they was made for and "Costume extra" - this is things like hats, glasses, bags and belts; items that easy can be fitted on other figure that it was made for.

Right now I have 61 runtimes :)
