I just noticed there's a tag: pots
Plant containers that are typically round
and a tag: containers.
Plant pots and boxes that hold soil and growing plants.
It sounds to me like the tag for Pots should be a synonym for the tag Containers. Especially since the tag wiki for Containers specifically mentions it includes pots, and the tag wiki for Pots calls them containers.
Is there something about pots that I don't know about that would make them different from containers?
