I would like to see badges support the badge-large class to make them large like a button, this would allow for large badges and oval buttons!
I would also like to see unordered lists support icons... something like <ul class="icon icon-star"> and then all the child <li>'s would have the icon in place of the normal disc. Last i would like to see support for larger icons, at least 24x24 and 32x32, and maybe even 64x64 Just a few ideas of mine.
