This addon automatically toggles the game's HUD settings for AP and SP notifications when all abilities or skills have already been acquired. The FIFO text telling you that you've reached the cap is also prevented. The following options can also be entered into a chat window:

/option BlinkNotifications false      Turns off the blinking effect.
/option BlinkNotifications true       Turns on the blinking effect (default).
/option SuppressAPWhenCapped true     Hides AP notifications when the cap is reached.
/option SuppressAPWhenCapped false    Hides AP notifications only when all abilities are acquired (default).
/option SuppressSPWhenCapped true     Hides SP notifications when the cap is reached.
/option SuppressSPWhenCapped false    Hides SP notifications only when all skills are acquired (default).

These settings are persistent and affect all characters.
