Honestly, it would be nice to have color-coded classes or elements in the Navigator panel.

If I create a Home, About, Features, etc. Sections and have them highlighted by different colors and have the sub-elements benefit from those colors...

I often get confused by which section I am in, regardless of whether the other sections are collapsed or not.

Having it color-coded (or monochrome for all of my color-blind individuals) would be a major help not only for ease of access but also would help keep things organized as well!
