I'm not mad keen on the 'inference' model myself, though I think I can guess
why it was done (degrees of freedom and synchronising UTR/CDS annotation
changes).  For my own purposes I'd rather have all features stored
explicitly.

Thanks for looking into it - I hope it doesn't require too disruptive a
change.  I think the best outcome - for me - would be to have Artemis exons
represent the exon in the db, and for CDS and UTR to be inferred as new
features in the gene model, with CDS locations corresponding directly to the
polypeptide.

Thanks again,

L.
