Ah, thanks for the tip.

The reason why I inquire is because a lot of my books are, I have the Forgotten Realms series, and a lot of them have sub-series, Kim Harrison's series, etc. But sometimes I don't remember which books actually come from a series because some of them show up as 'Kim Harrison - The Good, The Bad and the Undead' without a series or number. I guess I just want an intuitive plugin, yanno? Although this is absolutely amazing.
Unrelated, but could someone share with me an expression to add books that includes the series, BUT doesn't mess up authors who have hyphens in their names? For example:
(?P<author>[^_-]+) -?\s*(?P<series>[^_0-9-]*)(?P<series_index>[0-9]*)\s*-\s*(?P<title>[^_].+) ?
This is the one I am currently using, but, this is just an example. (The author's name does not actually contain a hyphen.)
For example, I add something like,
"Joyce Carol-Oates - This is a Series 01 - This is the title.epub" to the testing window, and it comes out as
Title: Oates - This is a Series 01 - This is a Title
Author: Joyce
Series: Carol
I've wanted to use [This is a Series] to separate series stuff so that these things don't happen, but I'm not entirely sure how to add brackets to the above key sequence. I'm sure it's possible, but I've not yet figured out how to do it yet lol. Because if I do, it would say:
Title: [The Hollows Book 01] - Dead Witch Walking
Authors: Kim Harrison
If I leave out the hyphens:
Title: Kim Harrison [The Hollows Book 01] Dead Witch Walking
Author: Unknown
Series: None
