Often I create a my variations and then go back and want to change something.



If you close the template you are then locked out of changing variations and have to start again if you need to make variation changes. Even if the item has not been listed.



If you for example forget to add a price for one variation you get an error message when trying to list. However you can not then go back and edit the incorrect variation. As the item is not listed you should still be able to edit the variations tab

I agree
