I'd like it if there was some kind of notification whenever timed special abilities become usable again, because they're not all always on your skill belt. Maybe an extra small version of the ability's icon could pop up in the far upper left hand corner of the screen, between the combat log and the buff icons (or even just a notification in the combat log itself {the combat log also still needs to be improved BTW; we need the ability to skip to the end and to view earlier entries}).
