This addon will automatically replace any buttons on your action bars when you change a talent. The addon can also replace spell names in macros but this is disabled by default. You can blacklist macros or spells that you do not want altered when switching talents.
The addon will save buttons on your action bar that are changed from active to passive talents. The addon will restore these buttons when the talent is changed to an active one again, as long as the original spot on your action bar is empty.
