Class Trainer Plus is an addon for World of Warcraft Classic that upgrades the Class Trainer interface, adding the ability to ignore, search, and train all.

You can ignore any spell offered by your class or pet trainer by right-clicking and checking the "Ignore" option. You can then hide them from view like the other available filters.

Easily find spells to ignore by using the search box.

When the Shift key is held, the Train button will allow all available, non-ignored spells to be trained at one time.
