I'd been meaning to get around to this for a while, but I finally did it: every character who has literature written about them now has an alert banner at the bottom of their profile with a link to their library, so you can tell that they do! Here's Amber as an example.

You should support Waltz's suggestion on the suggestion boards if you think there should be an official feature on Toyhouse to make it visible on characters' profiles when they have lit! :0

There's also no way to sort characters by most lit yet, so I made a tag for all my characters who have literature here (which also makes it obvious which characters don't yet... hmmmmm. Any characters you guys want to see me write about? Anyone spoilery I probably can't write about yet, like the Wild Dogs, but I'm open to all suggestions!).

(As a side note, I'm slowly working on getting five more new profiles up, after redoing Carrots' yesterday. Some of these are among the more important characters in the story! I'm finally up to the ones whose bios actually get into the plot of the comic. If you're up for hearing me ramble about this stuff, I do that a lot on the Catband twitter account.)
