Splaunchy:
Are you fond of command lines? Do you like to keep your screen free and clear of spells you don't use/need very often? Want to summon a specific pet without having to open up the companions window and searching through your vast collection? Splaunchy is a solution for these scenarios and more. Type in a few letters of what you are looking for on the left side, and it will display things that match on the right, with their icon in the center. Hit enter once to enter your text, and twice to use the ability that was found. You can even use it to open things like the Character window, or to change which language you use in chat. Just remember that it won't work in combat, due to the nature of the game's API restrictions.
