Wayne,

I tend to agree actually, as I have been developing this the less I think
having a BoM export is appropriate:

1. Separation of tasks - it's simpler and cleaner just as an editing table
2. Python (etc) is way better at data manipulation
3. External scripts are by design much more flexible.

I have some ideas for improving BOM output but I am now thinking they would
be best served not integrated here.

I will remove the buttons and leave those thoughts for another conversation.

Oliver,

I finally got a chance to test your patch set and was a bit surprised
what I saw after following the conversation on the mailing list.  I was
under the impression that this was a generic component properties
editing grid not a BOM tool which is what it really is.  I like the idea
of being able to edit component fields in table form.  I'm less thrilled
about the BOM export options.  For those of you who haven't been around
very long, Eeschema used to have a BOM dialog.  It didn't allow for
editing field values but it contained options for various BOM output
types.  Initially this dialog was simple and contained only a few BOM
output types and options.  Of course everyone has their own idea of how
a BOM should be formatted so gradually over time, the BOM dialog and the
underlying BOM output code became a huge mess.  It was finally decided
that the design was no longer maintainable and removed.  It was replaced
by the current system along with samples that provided all of the same
BOM output options from the old BOM dialog.  Except for the field
editing grid, your dialog and BOM code looks a lot like the original BOM
dialog.  I can see the same thing happening all over again.  Why no use
the existing BOM generation code in your dialog rather than re-implement
code that does the exact same thing?  I'm not opposed to field editing
part of the dialog, but I see the BOM output part heading the same
direction as the old BOM dialog.
