I would seriously bend over and kiss a boot if someone would put in sort and filter functions for build able structures. There is a search command which is about useless as the list resets back to default every time you click build.
how about something like
Storage - silos and houses tents
Decor - trees , signs, and other fluff
Crafting areas
Flooring
pretty pretty pretty plz?
PS: also plz include the structures statistics in the build window IE bulk/stack ammounts
