Thanks to
@SrBedRock request, I added a formatted verions of %griefprevention_bonusclaims% and for those who want to translate the unclaimed string (when using for exmple %griefprevention_currentclaim_ownername%) you can do that in the config.
I have added a placeholder that allows colors for trusted/non trusted/neutral in the current claim. This way the player know when he or she is in a claim he can edit.
Colors are configurable in the PlaceholderAPI config.
