extension, limit of the plugin

Hello,

Thanks for yur very good work. i realy enjoy your plugin.

But, i would like to sell some differents products, and i need some options on this products.

exemple :
photo selection (add to cart) then
> T-shirt -> sizes (5 sizes)

> Mug -> color option (black or white)

i can do as many product as options, but its not great.

Do yu see a way to do it with yur plugin ?or do i need to program it ?

Thanks for yur hard work.
