[Plugin: Mad Libs] Suggestions

Hi all, I’m in the process of writing a Mad Libs plugin for wordpress. I wrote one a few years ago as a standalone product, but have since decided to make it available to the WP community. I want to create both a lite version and a pro version, but need suggestions as to what you might want to see in it and/or what should be “lite” and “pro”

features right now include:

– Multiple Editions (aka Categories, or “Books”)
– ability to add affiliate sales link to the “hardcopy” book (i.e. a book that you entered from amazon’s store)
– unlimited puzzles with unlimited fields
– user submission of puzzles (or stories, which can be converted to puzzles)
– Bad word filtering
– Email link to puzzles to friend
– Email completed puzzle to friend
– Admin notification when new puzzle/story is submitted for approval
– Dashboard block showing puzzle/story submissions waiting approval
– Puzzle tracking (i.e. when a user does a puzzle, it won’t give them that puzzle again until they have completed all other puzzles)
