So I've had alot of new users who are just starting out their journey in Minecraft Server Hosting, and many of them are making small, personal servers. This means that they don't have much need or desire to use a permissions management plugin... but they also don't really want to op everyone. So I made an easy compromise. The new config file has "UsePermissions" (a new entry) disabled (set to false) by default. This means you don't need a permissions plugin to use all of the permissions features. !WARNING! This does mean that any player can create or delete or otherwise alter any warp. Use this feature with caution.
The other change to the config file is the addition of an entry called "Warp-Limit" which is by default set to 1. This is used if any player does not have a specific permission limiting their warps (warps.limit.x).
I've also updated the code to 1.17, but do bear in mind that I have not extensively tested any of this. Please let me know via Discord when/if you have issues or questions. My tag is Blue Dev#1111. See you there!
