It would be nice if we could better track buff uptime/activity.  Currently buffs are cluttered and constantly moving the buff bar as they expire or are applied.  It would be nice to have some way of setting a static position, or larger icon, or some graphic effect around the border of those buffs we're interested in.  For example this could be the monster AP buff from skill addons, a crit buff from some ability like succession zerk beast form, super armor effect from a valkyrie healing you or from an E buff.
