GokiStats is a skill improvement mod for Minecraft, it has been well-known before 1.7.10 but it has stopped developing for years.
Fell free to solve any issue with crash-report in GitHub Issues.
Upgrade from pre-1.2 version Mod:
PLEASE DELETE ALL GOKISTATS CONFIGURATION FILES OR FOLDERS IN CONFIG!
Why you still port it to recent versions?
Umm... Because lots of players have used to type 'Y' to open the skill menu, and drain their experiences.
Also, the interface provides is pretty and eazy-to-use.
Screenshots are available in the Images tab.
