Overall, I would agree. It is nice knowing the field properties in the attributes pane especially if you're not the one who created the data to begin with.
But I don't like the hovering where it obscures the fields and attributes. I'm not in front of ArcGIS Pro or Desktop at the moment, but it would be nice if that smaller properties window was affixed to the bottom of the attributes pane and then an option to resize the window down to hide/show it was available. Or, a check option from the top of the attributes pane itself.
