Feature description:
Right now the main navigation entries are not visible in the settings. I think it would be practical to be able to switch between settings and for instance the library view more easily. This is especially useful when customizing something and you constantly need to change back and forth from settings to another view.
Problem solved:
Right now you have to navigate the whole settings tree each time you switch back and forth.
Brought benefits:
Much easier customization
Other application solutions:
Most applications actually do it that way.
