create implication feathered_wings -> feathers
feathered_wings generally have feathers on them. The only reason I could see this not being desireable is if we want to keep feathers refering to individual feathers and expect users to understand that if they want feathered_wings, that's a diffirent thing from just wanting a feathers.
In the same vain I want to address two things. First, angel_wings, how do they relate to feathered_wings? Second folded_wings, this tag is only used once but a tag to refer to wings in a "rest possition" useful. By "rest possition" I pretty much just mean not moving, be they on a person or a bird like in post #1679776 and post #1670406 respectively. This would be as apposed to an energized state like in post #1674214
