It doesn’t seem like they have a better one still, but with CSS now you could apply a transform: scaleX(-1) to flip it 180 for a sneaky hack.
This is 5 years too late, just coming here to thank you for keeping this plugin updated and being so responsive to discussions about customizing it. I’ll probably fork it to add some of my own tweaks and codes in the future, just wanted to share my current thoughts on it.
