A very simple addon that calculates the kills, quests and battles required to reach your next level.

Features

• After each kill, quest or battleground, the exact amount required of that particular mob, quest or battleground is displayed in the floating error-message window, and optionally in the default chat window.
  
• A small window displaying the average amount of kills, quests and battlegrounds required, based on your previous data.
  
• A highly configurable LDB data-source, providing data to LDB front-end addons, such as TitanPanel and Fortress.
  
• Hunters can see the amount of kills required for their pets to gain a level.
  
• Optionally, the amount of battleground objectives needed can be displayed.
  

All of these display features can be configured via the configuration window, which is
accessible by either right-clicking the average window or typing the commands: /xtl or /xtolevel

Language support
The addon supports the English, French, German and Spanish clients.
It also comes with a Danish translation, which can be enabled from the in-game configuration window.

You can help improve the translations, or add support for non-supported locales, via the Localization tool at curseforge.com.
The addon also supports translations for languages other than those officially supported by WoW. If you would like to contribute a translation for an unsupported language, please contact me via Curse or CurseForge.
All contributions are greatly appreciated!

Special thanks to:
- Marcel and Axel for their help with the German translation!
- carignou and lalrobin for their help with the French translation!
- Xyrec for the Danish translation.

Note that the translations for the non-English locales may not be entirely correct.
I speak none of them, so I completely rely on your contributions... and the Google translator :)

Custom LDB Text Patterns
Since version 3.2.0_5r you can create custom patterns for the LDB text output.

This is done by opening the config window, selecting the LDB tab and choosing "Custom" from the Pattern drop-down. Then the text-box will be enabled for you to enter you pattern.

In short, you can use HTML-like tags to represent the available data:
- kills, quests, bgs (battles), bgo (bg objectives), xp, pet, petxp

For example, you could do:

- K: <kills> Q: <quests> XP: <xp>

= K: 100 Q: 10 XP: 90%

For full details on how to construct a custom pattern, see the "customPatterns.txt" file that comes with the addon.
