I have rewritten SHT from the ground up using the Ace2 framework. It's nice stuff. I've made it less of a mess and made it easier to add new skills for different classes.
This mod will time your debuffs on enemy mobs as well as other useful things, like how long till your trap arms, how long till your trap despawns, or how much time you have left before you can no longer do revenge.
You can group your bars using the group system. /st config or the button on the minimap for configuration.
