Parafly

ParaFly lets players fly but only inside the GriefPrevention claims they own or are trusted in. Flight switches on automatically as a player enters their claim and off as they leave, with a notification each time. A flying player is held at the claim border so they can't fly out into the wild, and each player can toggle the feature for themselves with /claimfly. Players who can already fly elsewhere (creative, spectator, or another fly plugin) are never affected.
