SpellbookExtended

Disclaimer: This addon is developed with the help of AI. 

Description
This is an addon for World of Warcraft: Forever, which is currently in BETA.
See which class spells and ranks you can still learn, and when.

Some skills may still be missing from this addon.
If you find any, please leave a comment and it will be added.

NEW: Compact Spellbook option available now!

A narrow, dense spellbook for browsing spells on the run, opened by the spellbook key instead of Blizzard's full-screen one.

Spellbook Extended adds a panel next to your spellbook. It lists every spell your class can still train, grouped by the level it unlocks at, up to level 60. Spells above your level are greyed out. If you skipped a rank at a lower level, it stays in the list until you learn a higher one, so nothing slips past you on the way up.

Each spell shows its trainer cost. The top of the panel shows what your next trainer visit will cost compared with the gold you carry. When you talk to your class trainer, the panel opens beside the trainer window with a "Train all" button.

When you level up, the new spells pop up as small toasts, like loot. Click one to open the panel.

A few notes:

• Right-click a spell to skip it. Skipped spells, and the ranks above them, are left out of the totals and out of "Train all".
• Spells taught by class quests or class books are tagged instead of priced. Quest spells also say where the quest starts.
• The panel also lists weapon skills you can still learn, with the weapon masters who teach them. Click one to pin its weapon master on your map.
• Parry, Dual Wield, Mail and Plate Mail have their own General tab.
• Costs are Classic prices until you visit a trainer. After that the addon uses the trainer's prices.
• The beta client doesn't load saved settings at the moment, so options and skipped spells reset each time you launch the game.

Settings
Find "Spellbook Extended" in Settings > AddOns.

• /sbe shows or hides the panel.
• /sbe test previews the level-up toast.
