Category Hint in Transactions Sheet

What happened with the “Category Hint” in the transactions sheet column?
How do I access it?

The Category Hint isn’t an option in the Foundation Template. Autocat is the preferred method of categorizing transactions since it allows users to set up their own rules set.
