GCD is an addon that provides a cast bar, global cooldown bar, swing timer and cooldown timers in a circular fashion around the mouse cursor or alternatively at a fixed position on the screen. If you find a bug or have any wishes for the addon feel free to write a ticket. Keep in mind that a lot of addons mess with the default castbar. Should the toggle for it not work properly its most likely that another addon modifies it as well. To open the options menu type "/gcd"
Adds a direction arrows status to Grid, showing the direction to your group members. To use it, assign it to any icon indicator. By default, the status will only be used on players more than 30 yards away from you; check the status options if you wish to change this number.
