I think it would be very helpful for some artists especially when making reference sheets for their characters or other specific drawings by using a mirror tool.

it would be so awesome, it would be so cool . . .

sometimes i just wanna draw someone facing forward without copying and pasting like eyes and stuff :3

A mirroring setting would be nice

we need mirror

Well, after some time of using Aggie.io.. I figured that there should most definitely be a mirror feature in here. It could be very useful!

Please, add a mirror feature!
