This is the official thread for my small addon CooldownTimers2 XSC.
XSC stands for Extreme Skill Cooldowns. It creates cooldown bars when you use a tradeskill that has an extremely long cooldown (like mooncloth, transmutes, etc.) The cooldown bars do persist through logging out and back in.
I don't have access to the SVN yet (still waiting), so the addon can be downloaded from here for now: removed, see 2 posts down.
