create implication levitation -> floating
To me it seems like levitation would be a subset of floating.
The wiki for flying defines it as "the act of being in or moving through the air with the help of a propulsion system (usually wings, a magic broom or a mechanical device)" and the wiki for floating defines it as "moving or hovering in the air, seemingly without the help of an outside propulsion system (i.e wings)". The difference is what is exactly causing it to float, so for example wings vs being controlled by an outside source.
Levitation seems like it would be a specific instance of floating then and would belong with images tagged as floating. Thoughts?
EDIT: The tag implication levitation -> floating has been approved by @Type-kun.
