The
changelog for Gantry 5.2.9
states a new feature of "New selectize field that list all pages / posts", but I'm not sure where this field is or how it is to be used.
Has this been implemented in any particular particle or somewhere that would appear in a theme's settings? Or, perhaps, is this something more on an API level, where it's useful to building custom items from scratch.
I guess I'm just trying to understand the significance of it, because in the
conversation thread in GitHub
where the idea was proposed, the people there seemed fairly enthusiastic about it.
