V0.5 (pre-release)

Major update:

• add a new command (/scompass) which use a book as interface
• add a second mode "180°" for compasses
• add tracking features (player, coords, position) with /sctrack
• split config and messages for easier translation
• code rewrited
• PARTIAL support for 1.12.2
• ...

THIS IS A PRE-RELEASE, I've some adjustments to do before release it, like:

• Add limitation by tracker type (not to have 50 tracked points at the same time)
• Other surprises ;)
• More tests
