This command saves the Project as a Template and should be moved to the Project Menu. I kept saving a file as a Template and wondered why it wasn’t in my Templates folder.
Alternatively, if most users are accustomed to this being under File, it should be renamed Save as Project Template…
This would avoid the confusion I experienced.
The manual could have the following added under ‘Creating Document Templates’.
“To create a document template from an existing file, create a duplicate of that file. Edit it how you like. Now drag it to the Templates folder.”
