I'm sure we've all run into the scenario where you make a perfectly fine skin, but then you check the side of the editor, and to your utter dismay it says the so-called front of your skin, is actually the back.

What I propose is a feature added to the editor that "reverses" your skin.

This could flip the sides of the skin, and replace the back of the skin with the front, easily fixing your mistake.

This might just be a me problem with not being attentive to small details.

Alternatively, there could be a toggle-able outline of the skin where the front is outlined in red, and the back is in white, and the sides are green, a bit like how Minecraft's structure block outline works.
