Healbot makes healing much more easy in pve since it gives you a new window with party targets in it... you can even show pets so all you have to do is click the bar on the Healbot window and that person will recieve Flash heal (left click) Greater Heal (right click) Renew (middle mouse) and you can set it up however you want. Its also great for buffing.. just click on the buff window and set up which buffs you want to be reminded of.
