So much needed

This functionality was needed for years. Thank you very much for creating this plugin. It’s a shame Automattic spend their resources making all the bells and whistles like new JS-admin and blocks instead of simple functionality like this so needed by regular users.
Being able to duplicate a variation is a great time saver altough all in all variation handling in WC is still slower and more troublesome than on other platforms.
Also you made a right decision to inegrate the functionality into WooCommerce standard interface – there are already several plugins creating additional interface only for this purpose which in my opinion makes the whole endeavour useless.
