Smart sections have options to configure the Fields, Filters and Sort, but they lack the Color option (like the one available in Views)
It would be nice if we can use this, to better differentiate between types, and when recursives end
for example:
In this image, we have projects, and Projects can have Products as well as Sub-Projects, and products can then show wiki pages.
We would like to add icons to Projects and Products, but that would mess with the clarity of Project and Products. Changing the background color of the different types / levels would help to visualize the levels, while also allowing for icons.
