Hi Greg,

very good question :-)

Oh, its also required for much smaller plans, I'd say. Although I don't
know alle the scary details, I had lots of discussions with devs in the
past. For example, when we've discussed the need for an "Outline View",
I have been told that the "Model/View" isn't clearly separated in
Writer. Thus being only one example ... so it will need major code
restructuring to provide a clean MVC.

This is one of the reasons why large-scale improvement proposals don't
help our development at the moment ... instead, it helps them to improve
the code iteratively and to refactor bit-by-bit. (Mirek addressed some
of these concerns with his roadmap, although the chunks are still too
large).

Although some people within the community might disagree: I think a
rough plan - a vision - would greatly help to communicate what we have
in mind in general. And whilst we have our development working with us
on smaller improvements, we could really make use of the given time to
resolve open questions like target users, high-priority workflows, ...

You've asked "Hope that makes sense?" ... Absolutely! Glad to have
people with your expertise around!

Cheers,
Christoph

PS: I'm terribly tired, so I'll skip any mediocre proposal how to
continue. But I'd be happy for any input :-) Good night!
