--- Comment #7 from Dave Gilbert <[email protected]> ---
Form editing in PDF has multiple meanings, and what people use LO for varies;
so hmm:

a) Using LO to overwrite a PDF with some other text, or a signature or
something - nothing special there; we just have to gently improve the PDF
loading.

b) Filling in the *fields* of a basic PDF form; again not that hard in
principal - if we can find fields we can probably turn them into editable
things.

c) PDF can have Javascript associated with field changes; for example I've seen
a government form that updates a 'total' at the bottom of a numeric column. 
IMHO that's a massive job (and even things like Okular are bad at it).

d) Saving a loaded PDF form that's had it's form filled in, such that the form
data in the saved PDF is stored in a way that a tool can extract automatically
as it would if the form was filled in  using another PDF viewer.   IMHO that's
a more detailed job; and harder to do generally - people would get very
surprised when they submit their government derived PDF form and find the
government misreads it. (Ahem I might have already had that happen using Okular
to fill in a Government form...)

So what to people use LO for editing a PDF for ?  IMHO (a) is what I use LO for
here, not (b..d) - b..d I use my Okular or Chrome for.

You could have a mode that was like the 'insert pdf' which uses poppler to do
*rendering* of the form and then you create editables for all the form elements
and do the stuff to do (d) - including (c) as well would be a big job.  But
again, IMHO I think (a) is what I want to use LO for when editing a PDF.
