Mind my grammar it's 1:30 AM right now and I'm about to go to sleep..
I've always thought that Blockland's Color Set Editor lacked functionality for Saving and Loading color-sets, the way the game currently works only allows you to control a single set of colors and to me it felt very cluttered after adding to many colors, so I decided to make a couple of quick edits to it and implement features to save / load color-sets and also rearranged a couple things... It's nothing special, but it works as intended. Also, I added a button that clears every color in the color-set box so you can have a clean slate to work with.
Just a quick reminder this Add-On is used to enhance the experience with the Color Set GUI used for avatar customization, not creating color-sets that you use to paint your builds.
