If the overview is there are a thousand little things and not a small
set of large scale specific projects then that's still a useful
overview. We could still sweep them into some general themes.

I wonder if it's the initial base screen (I think I might have replaced
some custom widgets there with more standard ones which might have
improved matters) or the "design view" rows/columns screen which is a
custom widget, but one I think that does at least have an a11y
implementation. In general custom widgets lead to forgotten a11y, like
the extensions dialog.

How about math? I see a bug 140659 for math still open linked to the
meta bug, which says "formula editor not operable with screenreaders",
but then the commentary seems maybe less bleak

Depends of what is being read out of course, missing labels for .ui
widgetry are super trivial to fix[1]. Something not read out from a
document can range from some small missing piece to some difficult
total lack of a11y.

My feeling is that category of problem is presumably relatively easy to
implement, there's a reasonable amount of general file format knowledge
around.

If Richard is ok with sharing that here it could help get a general
feel on what's lacking.

Yeah, right now I don't think there is a way to do it in gtk4. Basic
widgetry works fine and the internal gtk4 a11y looks good, but I don't
see what is possible to supplement it for document a11y. Its the kind
of thing I would probably be able to take care of when it becomes
possible.


[1] https://bugs.documentfoundation.org/show_bug.cgi?id=119931 is the
easy hack for those. Genuinely easy with valuable results. Not sure if
its completed by now.
