Image style copy or clone Is there a UI way to clone/copy image style?

/admin/config/media/image-styles 

lists all styles. I wish to modify one of them but I don't want to override it and I don't want to start from scratch.
imagecache_actions module implements this for D7 (brand new, in 7.x-1.x-dev only yet). It is based on a feature request for D8: #1403962. The dev version also implements a rudimentary export/import to copy between different systems (or the issue queue) without a need for features.
