Some document have a lof of headings. When I want to use right side panel to navigate I see only black, underlined text that is little messy for my brain. Finding what I need is a little difficult.

If there would be icons at headigns the same as in text that would be great. In object, in text I can add icon so for people like visauls like me this is great quick way to find heading that I want to. Maybe colors in right side panel with headings can be implement the same as headings in text?
