A plugin for displaying sticky posts based on custom taxonomy, order, and much more.
I thought this would make it easier to make a post sticky and make a cool widget, but I couldn't get the widget to work at all, it would always display that no posts matched my query, even though I do have some sticky posts. Disappointing. The option to make a post sticky is buried under visibility and you wouldn't know it was there unless you clicked on it.
Exactly what I was looking for!
