What's Training? is an addon for World of Warcraft Classic that adds a list of available trainer spells to the spell book, so you can easily know when to seek a class trainer out. Spells you already know won't show up.
If you have Class Trainer Plus installed, What's Training will show Ignored spells at the bottom.
- Rogue Poisons not working well, it will show available even if you don't have the required skill level in poisons
- Additional ranks for talents may or may not work, I have no idea at this point.
