Twinmum, one of the things I've noticed with houses I've downloaded is there is seldom a name, and the name of the creator, and a description of the build. Many of the houses in my inventory simply say "Lot" and what size the lot is, but no name and no clue who built it. This means if someone wants to use a build in a remake of a town or something that will be shared, there is no way to contact the builder for permission and therefor it really shouldn't be used.
When you click the export icon, there is an opportunity to name the build and write a description. It is important for builders who wish to share their builds to use this so others can tell at a glance who built it and whether it is something they truly want to use. This was a big issue when we were building Union Cove and would make it a lot easier for any future efforts along those lines.
I updated Pretty in Pink to fill in all the info gaps and added Pretty in Pink 2.
