Seriously I love that they added cards and dropped Panels and Wells. I used to have to create something like cards on nearly every project and used Panels/Wells maybe once.
Agreed! What I like about Bootstrap's development is giving people the flexibility to jump into something new like panels/well & then look for other plug-ins/hacks to customize the experience. Once those trends become more mainstream, they do us all a favor and incorporate them more cleanly. Cards are such a natural extension for a responsive layout.
