In conjuction of this idea:
https://communities.bentley.com/products/microstation/i/user_interface/references-by-subject-with-colors-in-reference-menu
We could have the same principal for References, Models, Levels and Named Groups. This way we would place the same color for things related to a determined subject. Saved views already have something similiar but missing the color theme.
Views have some potentiality but some properties are missing from the Saved views dialog, so first they should be placed there and then we could change order by color.

Mockup for Named Groups (the same should apply for other dialogs like Models, Levels):

As you can see we can place some Hierarchy to the left which is great, but to the right we don't have a proper helper for order apart from Description. We could have Discipline to maintain the same title from Saved views

And we could have the possibilitiy to apply a color to Structural groups, another color to Electrical and so on. This way we could find a lot faster what we need.

The color bar could be apply all along the line instead of a single column.

And gives the change to definte transparency for this color.
