Pcbnew footprint library management documentation is confusing.

The headers in the pcbnew footprint library management documentation is confusing at best. The header for versions prior to the stable 4 release states "Managing Footprint Libraries: legacy versions" makes it sound like this is how your manage legacy libraries in any version of pcbnew. The old library list dialog box shown isn't even available in the stable 4 release. The heading should read something like "Managing Footprint Libraries (prior to version 4)" Conversely the footprint library table heading is "Managing Footprint Libraries: .pretty repositories" which suggests that this is only for managing pretty footprint libraries which is also not true. This should read something like "Managing Footprint Libraries version 4 and later".
