Works well on 1.21.1 but it doesn't work in versions ahead of this. Despite this, the plugin proved to be very optimized and useful for quest GPS among other features.

It works well for me. I was waiting a GPS plugin for 1.21.1 and this one really satisfied me.

It's a simple plugin, it still lacks commands to create points faster, as well as something to prevent errors if you're in another world using multiverse or other multiworld plugins. But overall it looks very promising.
