Hi, Here is a suggestion for the visuals of text style changes:
Tracked adding and removing are both colored. It also inserts a line with the text: underline (slightly lower than default underline) and strikeout. Maybe a simple way to mark text style changes is to just use the same color as for adding but without underlining?
Of course it will not possible to see at a glance color changes that way but that seems a price worth paying and it is a price other writer applications like Libre Office and MS Word are willing to pay.
