Considerting bug#32062 [1] as well, it might be nice if AUCTeX offers a
way to customize `LaTeX-outline-name'.
I incorporated the idea of Omar, the reporter of bug#32062, to make up
the attached patch. With this change, you can prepare your own function
to extract titles of \section etc. or \begin{frame} depending on the
context, and use it for `LaTeX-outline-name-function' like this:
(defun my-LaTeX-section-or-frame-title ()
...
SOME FUNCTION TO EXTRACT TITLES OF section OR frame
...
)
(setq LaTeX-outline-name-function #'my-LaTeX-section-or-frame-title)
I didn't test my patch. I'm sorry if it doesn't work.
