As you might know this addon is no longer maintained by the original author, this is a fork of Gatorsknight's version "XtoLevel Future" for World of Warcraft Classic.
All credit for the Addon Goes to AtliThor
A simple AddOn that provides details about your levelling progress, tracking a variety of items required until you reach your next level.
Tracks the following:
Mob kills and Quests.
Dungeon runs.
Display Options
A small, configurable window, showing averages needed to level, a mini XP bar, and a time-to-level estimate.
A "floating" message and/or a chat message can be shown when XP is gained, to show exactly how many more such gains are required to level.
A highly configurable LDB data-source, providing data to LDB front-end AddOns, such as TitanPanel and Fortress.
Configuration
All of these display features can be configured via the configuration panel, which is accessible in the Interface/AddOns window, or simply by typing the commands: /xtl or /xtolevel
