This update is focused on fine tuning the simple mechanics of the plugin to allow more precise control over item protection. For one thing, you now have the ability to set item protection on a chunk-by-chunk basis in addition to the already existing world-by-world basis. There have also been minor improvements to the JSON storage that may or may not require you to delete your worlds.json file before updating to this version.
Also, I've created a basic config file that allows you to disable and enable protection caused by explosions depending on if they are caused by creepers, fireballs, TNT, or withers. There is also an item filter in the config that can act as a blacklist or a whitelist. For example, using the filter as a whitelist, you could make it so the plugin only protects diamonds dropped on the ground. Using the filter as a blacklist, you could make it so the plugin protects everything EXCEPT diamonds.
Hopefully this added configurability will make this plugin much more versatile and useful. Make sure to leave a rating if you're happy with my plugin! Thank you all!
