That is of course a problem.

I was going to suggest that "too big for 15" screens" was less of an
issue, than the actual resolution in pixels - but this depends on
whether the font and menu sizes are being scaled with the screen's
_physical_ DPI. I can't recall if that is the case or not.

Since people wanted to reduce the number of items in the preferences
menu, so if that were done - perhaps a few categories might have a
place. Dividing the long list into a few pieces IMO makes it more
navigable than one big long list without the space occupied by the
headings.

The XDG menu spec does have some adjustments to control how many items
are inlined before they get their own sub-menu. For menus (e.g.
"Electronics", or "Sound & Video"), I wonder if a different heuristic
would be useful.. you don't want to inline a heading for categories
which have just one item in them. You'd probably want to group such
icons into a virtual "Other" category.

Of course, we'd only show inlined headers if there are more than one in
a given menu.

The rules do become reasonably complex quite quickly, but I figured it
might work more easily for the preferences menu where the platform ships
most of its contents.
