I'd like to post a random post from a single category in my sidebar. (Like a quotes widget, but from a category.) Failing that, I'd like to post the most recent post from a single category in my sidebar. (If you're curious, it's a category with relevant book reviews.)
I think I'm about ready to learn to hack a plug-in, if anybody wants to coach me through it. :) I have the Category Recent Posts widget, but it only shows the title of the posts. I want the whole thing, including image.
Any advice will be most appreciated!
