Use a cipher to biject between the index and the uuid (make sure it's valid). Make a custom scrollbar to render a row of uuids from any given index. The search function is done by finding out all possible positions the patterns can be at, then generate a list of valid uuids that adhere to the pattern and jump through them in order. The search is not perfect because it doesn't find the actual "next" matching pattern, which is likely impossible due to the cipher used. A brilliant piece of art!
