When I view instructions in my inventory list, the title is prefixed with
' (Instructions) for Set ' ....
I think it would be helpful if this was done in shop listings, as currently the
only indication that the listing is for just the instructions (apart, possibly,
from a very low price) is buried within the breadcrumb hierarcy of categories
below the listing, where it follows the words 'All Items', which to a
newcomer to bricklink could be taken at first glance to mean all items in the
set.
Otherwise the listing reads exactly the same as one for the whole set.
This has caused me to double-take on a listing on more than one occasion whilst
browsing shops.
