Quite a few mods have obsolete buildings in them alongside updated versions (obsolete versions kept to prevent people's game breaking if those buildings were already in use).

Would be useful to have a building.ini option to tell the game not to list a building in the UI (maybe it could still appear in the Mods sidebar search) to hide obsolete buildings.

I know there's option in Mods menu to show only Favorites in the menus, but that would need me to mark dozen and dozens of assets as favorite which kind of defeats the purpose of that option. Maybe instead there could be a "hide" button in the Mods menu where I could choose which assets I don't want in the normal menus.

The building.ini option would just be way for a mod creator to default their obsolete buildings to hidden in the menus.
