Grouping/furniture save tool.
Select a group of/multiple items and save it to your inventory or a ‘personal catalog’ section. You can then place that saved group in any builds- be it your own plots or someone else’s. This would be incredibly beneficial for builders who use basic shapes often, and would make building much less repetitive- therefore more enjoyable!
