Errr. Multiple collections work in the plugin. I thought I chose the comma-separated text type for the collections column, but when I (eventually) checked it, it was just a regular text column.
I think I'm getting the hang of all this, though... I now have a workflow (using Collections, Goodreads, Reading List, and Manage Series) that ends with book titles like
- [A01] Bellisaurus 05 - The Tide of Victory
- [A02] Aldenata 02 - Gust Front
- [A03] A Logic Named Joe
- [B01] Ring of Fire 04 - 1634: The Bavarian Crisis
- [B02] Ring of Fire 05 - 1634: The Galileo Affair
in my "To Read" collection.
Thanks guys! Now where's that Paypal button..?
