A feature I also find very helpful is the locking of an image to prevent accidentally changes.
In stressful phases or when several people are involved in a project, it can happen from time to time that an image which has already been completed is accidentally changed. In this case, I think it would make sense if this variant is automatically cloned.
Many thanks!
