Yep. I added it. Many requests later - /rename is officially here!
Simply use /rename <new name> while holding the desired item for renaming, and our beloved, nifty GUI would open, letting you customize every aspect of the item's name!
You can view the new name before saving it, so you can go back and make any changes you want!
*Make sure players have the prismaticcolors.rename permissions

To accompany this addition, a new player data structure was implemented.
Better, faster, and more versatile! If you don't notice any changes that's great! Please let me know if you find any bugs or problems!

2.2k downloads! Thank you so so so very much!
I am glad many of you like this plugin as much as I do, and use it daily to enhance server gameplay! I still got (many) ideas at my bank, but I always love suggestions! Let me know if you have any

One last thing... I am working on a new exciting plugin, the only hint I am giving for now, is that it involved lots of math...

Stay tuned, it's going to be a blast!
