This addon puts all of your tradeskills under one button. It also has a couple of other features.
It will configure itself according to the abilities of the current logged on character. Drag the button wherever you want it using the right mouse button and drag action.
The interface options features include a scale to shrink the button. Also there you can find a checkbox to turn on the shutup feature and the auto decline duels feature.
The shutup module automatically turns off the yell channel in major cities. It returns it to its previous setting when you leave.
Among the buttons are also your health stone and a reset UI button.
