Card Game Framework

Currently I’m working on a framework for card games. I’ve started yesterday and progress is pretty good. With my summer vacation coming up, I think about developing it further.
The framework is 2D only and uses PaperSprites for the cards. It can display cards and animate them (moving and scaling). And now I’m working on deck handling (spawning cards, shuffling etc.)

So I’m curious if there is interest in such a framework. What features would you like to see? What would it take, to make you use my framework?

Sooner or later I might also ask for help with creating a sample game.
