This may have been suggested before but as a new player looking at the survival guide it's incredibly overwhelming. The guides are nice and ordered so going through those gives me a good idea on how to progress, that's not where my issue lies.
The blocks and items guide feels like a complete maze of every block thrown in a list, so my suggestion is the ability to filter it. As an example being able to filter by 'era' or filtering out any blocks and items you can't make. I only just found out I could easily make tool racks because I was making a crude shield (which I only found out through a friend), being able to look at the list in a filtered fashion like that would help streamline the entry into the game a bit better I feel.
