I hope you give us the manga that you are working with.
So we can read it too.
I mean... sure I can just filter by your name but does we agree seeing that in your credit pages are easier?
... in my univerisity and real life experience, there is one thing that must never be done:
ERASE/DELETE/REPLACE/EDIT old stuffs
Just make a copy and erase/delete/replace/edit the copy.
Save anything you edit with new name and my standard name will be [file name]_DDMMYYYhhmm
P.S. no i don't...
