I have lots of modifications to my templates, that if one day I decide to change them to default (or for any other reason I decide to back to its default mode), I should start reverting them all.
But if I do them by add-on, I can change it to default easily by disabling add-on.
Is there any sample code or tutorial? If anyone knows how to make such simple add-on, appreciated if you share its tutorial with us.
Thanks in advance
