I wrote this addon in 2009 for a halloween event on the VentMob servers and made it publicly available as a bit of an afterthought. It now has nearly half a million subscribers.
This started off as a refactor of Devenger’s STOOL that I made because I needed more features than the original offered, and I released my changes as a gift to the community.
Over the years I’ve kept it (mostly) running on whatever the latest version of the game is, fixing bugs where they come up (and occasionally adding features when the fancy takes me) without thinking too much about it.
Now it has nearly 500k people with it installed and every time I touch it someone’s game breaks which is not remotely fun any more.
