Classic
What it does:
Pretty straightforward - an addon that shows on the default castbar how much time is left on a spelllcast.
How to turn it off:
If your ever wish to disable it just delete the folder at World of Warcraft\_classic_\Interface\AddOns
Menu is still TBD as part of an UI toolkit I've been working on for casters, mainly Warlocks.
