I use a multimedia theme and the WP e_Commerce shopping cart. I installed this plugin and it worked immediately and perfectly. I didn't have to do anything other than activate it. It took my sticky post and placed it at the top of the associated category – right where I want it.
(Note that I don't have sticky posts on my homepage, and my "blog" pages are all based on categories, so I suspect I'm perfectly set up to enjoy the simplicity of this plug-in.)
