My favorite init manager was DMGenie for 3.5. It could track anything, including spell durations, and it had built in support for selecting multiple entries in the init list and rolling bulk saving throws, including the application of damage for those who failed or succeeded (and took into account evasion for Reflex saves). But that was a long time ago. (I've started twice on an init manage for iOS but real life gets in the way. Some day, when all of these games are obsolete, I'll finish it.
