Hi Jimm

for the plugin! I keep my library only for Fanfic, basically, so this is very very helpful

Would the replace metadata not work for, say, publisher?
I wanted to do this, but it seems I'm not getting any changes, or maybe I'm not doing it right.
Code:
replace_metadata:
publisher=>archiveofourown.org=>Archive of Our Own
the second is the publisher you get by directly using AO3's download options on their site and then adding the book to Calibre. Most of my 1 chapter fic are like that, while I keep the copy I get from FFDL for the multi-chaptered ones because those epub downloaded from AO3 are always missing chapter notes (HUGE bug and they know it °_° ) while with FFDL I get all the notes

(Why am I keeping those with 1 chapter as they are from ao3? because I like their "first page" formatting *see pic* and I try to keep it in as many fics as I can, not because I don't like what your plugin does!)
