Playing with card toolbar and some states

I’m working on the new UDCard and I’m playing with the idea of card toolbar with some build in options.

the options of the toolbar: style ( like color), an icon in the left corner, title, the options to add custom buttons to it and 2 builds in buttons.

Collapsed Button & Reload card content.

one more thing I added a hover effect to the card.
do you think its cool? ( i think it soooooooo cool.)
