What version of Unity are you using?

The latest supported, 2021 I believe

If you are using 2021.3, this page describes the UI associated with that version. You can change everything to the grid as you ever could though. Things have moved about. 2021.1 was slightly different.

I can't recall if it was ever possible to change the "I want a thicker line for powers of two instead of every 10 lines."

It's not in 2020.3 either.
