Greetings,
I am frightened ! I wonder if i have to restart everything

When i started to build my calibre database, i made the choice to work with MOBI files as default files, because i own a Kindle PW.
But when i tried to find a solution to add my calibre cover to my exported ebook, i found that it was possible by using the "modify epub" plugin.
So here my 2 questions :
- Is there a way to do the same to my MOBI files ? (even if i must do a MOBI->EPUB->MOBI conversion)
- Is there a way to convert all my MOBI files to EPUB ?
Now that i know how Calibre works, i would never made the choice to work with Mobi as default files
