It uses two code Block algorithms by @gordonlu310 described and shared in his post here:

[FREE] ListUtilz Extension - A powerful lists management extension

I'm sorry, I hate to break it to you, but almost every single block in this extension can be replicated with built-in blocks. Here is my approach in some of the blocks, there are still more that I haven't tried but can be replicated. Still, nice effort. (gave a like) [blocks]
