The document with an overwhelming LaTeX-based sections or subsections would be difficult to navigate with the outline, as the LaTeX codes have not been rendered.
The LaTeX codes in outlines pane could be rendered.
I would also find this really helpful if possible, generally speaking all possible latex support would be appreciated by me!
I was just about to post a similar feature request (though I’d personally consider it more of a bug report than a feature request).
Ideally, latex should also be rendered in the file explorer, to allow for file names using latex, and then also in graph view. It’s hard to organise a math-based vault without such features.
It appears this feature request has been rolled into Show Preview-rendered text instead of Edit-rendered text in the Outline - Feature requests - Obsidian Forum.
