can't believe this is still not in core!

This plugin hits the spot.. does what it says on the can.

I’m a bit concerned that it is different enough to the standard UI that I think clients may get confused.

This is working (and maintained) where Scissors / Scissors Continued is not.

A tip: set Box-crop to true on your custom sizes to lock aspect ratio when cropping, otherwise the sizes come out higgeldy-piggeldy (technical term).

Thanks!
