- Use Qt 5 connect syntax. - Streamline code, remove unused members. - Add a context menu for copying and opening the URLs. - Add const to XML code. - In the XML code, show the use of QStringLiteral in static inline functions to create strings versus QLatin1String in comparison overloads to avoid allocating strings from const char * literals.
