Hey so, heres the new stuff I for sure added this new version (Things I may have added right after releasing 1.6.6 evade my memory lol):

• New command goop delay that executes another command after some ticks.
• New advanced renaming sintax consisting of "Name Variables" that supports Placeholders in names (if anyone ever needed that lol), allows anvil renaming to target lore or only a part of the name, and some complicated naming of items.
  • Allows for color codes renaming through anvil, use permission
    gunging_ootilities_plugin.anvil.colors to restrict this.
• CustomStructures now differentiates between players sneaking; so that you can set structures to react when players shift+click or such.
• Also CustomStructures, now you can match signs that have a specific word or text (similar to essentials' repair signs). Only one line supported tho.
• Advanced MMOItems converter settings, so players can craft items of random tiers (and with stats depending on the tier).
• Much more easily limit the amount of times an OnApply command can affect the same item (used to be through scoreboards and a mythic skill, At one point it seemed easy enough but I now realize it is quite cumbersome). Requires latest MMOItems dev build

And a few bugfixes.
