I wanted something more than the little thumbtack icon to the right of a thread title to visually separate sticky threads from "normal" threads. This is exactly what I was looking for. It's a subtle feature that enhances the user experience.
I changed the "phrase" for the "normal threads" header to "Current Threads."
I was tempted to change it to "Abby Normal Threads!" (A movie reference - Young Frankenstein)
A very nice freebie add-on! Thanks for doing it!
