So you have to use the mouse?  That's a pretty severe limitation and
would make that (as a general design) pretty useless.

But we could have it as an option, I guess.

So if we have a fold-text.el library, it could offer

* fringes
* buttons
  * svg
  * emojis
  * other random text
* "..."

or a combination of these, and then have some kind of fall-back system
(i.e., if you want fringes but they aren't switched on, then fall-back
to button), or something (that the user can specify).

(And similarly, fall back from svg to the other things when that's no

(domestic pets only, the antidote for overdose, milk.)
