I'm following a Peter Quint's tutorial.
At some point he opens the Display Options and under Guides & Markes, he clicks on Custom in order to create an Attribute Text.
In HD14 this option is not there anymore, although even the official help mention the same steps in order to get to that custom drop down menu.
So, where's this Custom menu?

They were replaced by Visualizers
