I'm somewhat of the opinion that this would qualify as 'dumbing down' and lead a slippery slope to questmarkers or ! and ? above questgivers, levelscaling and other modern 'conviences' which ruin gameplay.

I haven't had any trouble with trading out items to identify, and with the latest patch simply dump all stuff in the trade window then scroll to the barter PC before adding gold to have barter used by the highest barter skilled person... ?
