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.
Version 1.2.6 and 1.2.7 fixed the annoying de-sync bug, please use the most recent version.
Mod for 1.15.2 has come out! Try it out.
Why you still port it to recent versions?
This mod provides a progressing skill upgrade system and a convenient interface, which is casual and helpful for your whole game playing experience.
Screenshots are available in the Images tab.
