While I was thinking of it, I have a feature request for this plugin.
On children's books that have an age range listed, such as:
Could you turn the age range into a series of tags?
So that a book that says Age range: 4 - 8 Years
would get tags of:
Age4, Age5, Age6, Age7, Age8
This allows a user to quickly and easily select a tag that corresponds to the age of a child.
I currently do this manually for the children's books in my library (although I "convert" to grade level instead of age).
Anyway, just a request, and thanks again for your work on the plugin.
