We sometimes hear that trees are currently to generous in the visual appearance. A denser appearance would allow to view more rows at once. On the other hand, a generous appearance benefits occasional users and users working with mobile devices.

There's typically no best setting for tree density, but there's a lot of value in allowing the user to choose the density level at which she would like to view a list or tree.

We've thus developed a way to allow a user to switch to different list/tree densities there.
