We have been testing this feature extensively, and are happy to announce that this is no longer an experimental feature.
In the settings.yml, you can enable/disable the plugin automatically enableing/disabling flight mode for your players when they enter/leave a claim so that they dont need to use the "/claimfly" command to enable flight.
Added new config option to automatically enable/disable flight mode when entering/leaving claims (based on permissions), by default this option is disabled but can be enabled in settings.yml >> ClaimFly >> AutoAllowFlightOnEnterClaim
Added config options to ignore players in creative or spectator mode.
Fixes:
Corrected permission required to use the /claimfly command
