This addon is _not_ updated for WoW 4.0 because this feature is now available in the default UI under the filters button.
OnlySkillups adds another filter possibility to the Tradeskill window.
The filter can be toggled with the new button left to the "Have materials" checkbox. When enabled this filter will only show recipes that have a chance to give a skillup. This makes it easier to find those recipies that will improve your tradeskill level, but are lower in the list.
- The buttons state is now also remembered per tradeskill
- The buttons state is now saved between sessions
