Completey agree. I am managing more than 100 users from different countries. Currently I have to maintain > 5 templates per language (e.g. english template 1, english template 2, english template 3 …). Instead I would prefer to just offer an english master version containing “all modules” and have the user decide which modules to use in her/his email.
The Design Manager already works like this (delete/clone modules within tempalte). Why not the email editor???
