What do you use column icons for?
Here are mine:
- Instead of leaving an undefined boolean blank, you can put an icon there to match the checkboxes and x's.
- Metadata issues. No pagecount? It'll show an icon. Forgot to delete an ORIGINAL_EPUB? Another icon. Fanfic hasn't been updated in a few years? Another icon. It's helpful for quickly sorting out issues that land a book into my Cleanup virtual library.
- Reading status. I have a boolean yes/no column for #read, but I heavily use icons. If I'm currently reading the book, a bookmark will appear there. If it's on my reading list, it'll show a little clipboard. I've also got a specific icons for fanfics that have a new unread chapter.
- Device status. If a book is on my Kobo, it shows an icon. If it's on my send-to-device reading list, it shows a different icon. If it's a Kobo Store book, it shows a DRM lock. If it's a book borrowed from Overdrive, it shows a library icon.
Here's my reading status and device status columns in action:
(Curious about how I did the chapter count on the fanfics?
Here you go.)
- Fanfics. My Fandoms column shows icons for various fandoms (including generic book/film/game icons for ones not warranting their own.)
- Formats. Instead of having a long text list, I just have a set of icons.
