I would love to see a timer that would appear much like the initiative bar, where you could enter the buff/debuff affect and rounds/time it lasts. as the initiative bar is moved along by the gm, rounds and time are calculated by reaching the player who's turn started the affect, calculating one round. Playing a cleric, the buff duration is often forgotten or hard to track. Also the ability to target players as this is set up to show who, or what, may be affected by said affect.
