Weapon Swing Timer - Sixx Fix
Continuing my improvements of the WST addon originally by LeftHandedGlove. Huge thanks to him for starting it! Description from original WST for simplicity.
WeaponSwingTimer is an addon for WoW Classic that tracks your's and your target's swing timers.
If you're a hunter, it tracks Auto Shot timing and castable shots cast time.
If you use a wand, it also tracks when your shots will go off.
Melee Bars
The melee bars track the player's and target's main-hand and off-hand swings.
It resets on abilities that would reset a swing timer, such as Warrior's Slam, and also takes parry haste into account.
Both frames can be moved around with the typical click-and-drag.
A configuration window can be brought up with /wst where more visual options are available. 
Hunter / Wand Bars
The shot bars track the player's Auto Shot / Shoot timing and also track the cast time for Aimed Shot and Multi-Shot. The shot bar turns white when an Auto Shot / Shoot projectile leaves the player.
While the bar is white, the player can move and cast freely without clipping their next Auto Shot or Shoot.
When the white bar is depleted, the player should stand still while their Auto Shot or Shoot is 'casting'.
