In a similar implementation from the Navigator and the Transformer Gallery pane, it would be nice to have a search box that would filter the list of attributes or attribute types on the Feature Information pane.
During data exploration, JSON, XML, and flattened semantic data can have many attributes and lists. It would be nice to shorten the list in the Feature Information pane without minimizing the attributes in my canvass. A good sample to filter would be "Date" if there are many and labeled with suffixes and not as prefixes.
