Hello,

I have updated from version 11 to 12.1 and I am wondering how can I use Template extensions saved in the root folder called "template-extension".

In version 11 there was a menu in Admin section where you was able to assign your customized template to overwrite the original template. I believe you already know what I am talking about...
I am not able to find this menu in version 12 anymore. Was it removed intentionally?
