Hey sorry for the confusion but this isn't my project! I just found it last night while researching b-trees and figured I should share. I now realize that the 'Show HN' prefix means one is showing off their own work. My mistake!

I was excited to come across this work because I was hoping to make something similar to show how a parser builds an abstract syntax tree.

After playing with it for a minute I agree about it needing an auto run feature!
