I'm currently working on manga, trying to get the titles and metadata entered correctly. So I'm using colors to highlight various error condition tags. For instance:
- Authorless: books without author info within the file itself (no title page, credits, etc)
- Error: read error when trying to open the book (file download errors which only appeared after I started viewing files)
- Chapter Order: books with chapters out of sequence (3,1,2...)
- Renumber Pages: books with pages out of sequence (1, 10-19, 2, 21-29, 3...) (Remember, Windows handles numbers as text within a string so "alphabetical order" differs from "numerical order")
- Change Format: convert zip/rar archives to cbz/cbr
Coloring these tags makes it easier to see which books still need additional work. It's a kind of visual "red flag" while looking through the database.
Additionally, I use:
- Unknown Author (crimson) which is the default input when adding a new book
- Delete tag (orangered) for those occasions I'm almost absolutely positive I've got multiple copies of a book - but want to double check (page by page comparison) before destroying it
