works almost perfectly, my only complaint is if a series has more than 20 works it seem to only download up to 10 of them

Works perfectly. Downloads everything quickly and in the order they're supposed to be in (though I personally add the corresponding number in front of the name just to be on the safe side). It's been immensely helpful for some of the longer series I've been saving!

**I see that a common complaint is that it doesn't merge all of the series into one file, and I feel the need to remind you that the series is still individual fics. They are not chapters. Even if they are related to each other and listed in a chronological/chapter style, they are still posted as their own individual works and thus will be downloaded and saved as such. Please keep that in mind before using this, the creator made a great tool and it does exactly what they intended for it to do :)

Great addon! :D
Can you make an addon that does the same but for authors/profiles works?

As others have said, I wish it merged the epubs and allowed me to choose the save folder. But I appreciate it anyway. Some of the series have a crazy number of chapters and it's nice all I have to do is add to Calibre, sort the Series column, and merge with the epubmerge addon. Instead of doing all that AND painstakingly opening and downloading every book in a series book by book.

A good extension, it saves time.

Cons :
- Stories stay split from one another and you have to merge them using Calibre (to put them in the right reading order). To merge them into one file/ebook would be better.
- You can't choose to download you stories in a specific folder on your computer, they automaticcaly download in the "download folder"

Thought this would merge the series into one ebook, now i have 40 ebooks in my downloads folder...
