Ability to set different colors for notebooks

[XCS]

Currently all notebooks/items in the sidebar have the same color and no icon, make it hard to skim through them.

Ideally you could set a color for each notebook name and all it's children would inherit that color. So, for example, you could change the text of those items to red, or add a red indicator before them:

You can sort-of do icons now by using emojis.

This might be simlar to what you're trying to accomplish.

Theme request: Subnotebook shading

Thank you so much! That works perfectly. I may darken the last color and add some more, but this is working for now: .list-item-depth-1 { background-color: #213952 ; } .list-item-depth-2 { background-color: #214A6B; } .list-item-depth-3 { display:table-cell; background-color: #315A84; } .list-item-depth-4 { background-color: #356EA3; }

The implementation could be similar, but the idea is different.

I don't care as much for the indentation/nesting level as the grouping of notebooks to make it easier to find the notebook you are looking for.
I want for example to have all personal-related notebooks to be green, all notebooks related to business be blue and all gaming-related notebooks to be orange. (just an example, not my actual use case).

Another example is how Onenote shows tabs at the top AND each top has a different color.
If all the tabs were the same color it would have been a lot harder to find the one you need.
