Configuration tools
Hopefully, the settings cover all of the main areas of the system and its appearance.
Ubuntu Studio and Kubuntu are both KDE-based distros, and KDE now groups all of the configuration into a single application, which is searchable. Having a central location for the settings doesn’t come with any real disadvantages. The configuration tools cover all the common areas of the interface along with system settings in areas such as network setup. The various settings show up in the launcher’s search results as well.
