Well, if the name isn't obvious enough, BuffTimer is a timer for EverQuest beneficial spells, a.k.a. buffs. It automatically calculates buff-related focus items and AA, and alarms can be set for when buffs are close to dropping. Up to five buffs can be timed, and the list of spells is completely configurable.
For future versions, I intend to make alarms more flexible, allow spell duration to take character level into account, and possibly to allow timing buffs based on a log file. Additional feature suggestions are always welcome.
The latest version of BuffTimer is 1.0.2 (released May 15, 2003), and is currently available for download.
