Basic Buffs is a simple Buff watcher. With the default settings, it will automatically track buffs that you cast by examining the buffs applied to you and alert you with a popup message at the top-center of your screen 5 seconds prior to a buff dropping, and a separate alert for 5 seconds after the buff drops.

/bb off: toggles buff watching off. Also clears any persisting alerts
/bb on: toggles buff watching on. Also resets the list of abilities the addon uses to determine which buffs it should be tracking, as well as any other lists are being held.
/bb topc: toggles to Track Only Player Cast buffs to on. Default setting is on.
/bb all: toggles to track all buffs that you are capable of casting. Opposite of /bb topc.
