It's hard to find the waystone you want when there's no search feature.

Yes!

A search is often seen as a very complex mechanic, what is the intention of this? Just implementing a search bar that utilizes the default Java string.contains(); Or some custom actual useful search like fuzzy searching?

If just relying on the string.contains, I can add this.
Last question would be where to place this search bar.

Just made a PR for a very simple search bar.
