thanks again
I know that using child themes this "problem" does not really occur - but this is not what I need.
I simple want to backup / archive or whatever the
whole theme with
all template adjustments
Either to have 2 servers (dev / prod) to work on themes or else.
And I don't want to keep looking at red or orange flagged templates, they should all reset and be like a clean, new style
But I guess there is no alternative
