Jonas's magit-section (available on NonGNU ELPA) more or less does
exactly that: on the GUI, add chevrons to the left fringe (right chevron
means "hit TAB to expand", down chevron means "hit TAB to fold back");
on the TUI, append ellipses to expandable sections.

It's not 100% feature-complete (IIRC it does not fall back to ellipses
on GUI when there's no fringe, and it has no mouse support), but FWIW
I'd love for outline(-minor)-mode to behave similarly.

(This might have been mentioned in the thread, but Juri recently
introduced describe-bindings-outline, which enables outline-minor-mode
in C-h b)
