A key feature that seems to be missing is the ability for comicbase users to see how many Atomic Avenue wish lists a comic is on and also run reports in the tool on that info. Providing this functionality could really help sellers/collectors know what books are highly sought after and better link buyers with sellers through increased numbers of offerings where there is the greatest demand.
This general feature is available on sites like mycomicshop.com.
The data could probably be displayed in the upper right of the comic titles/issues screen along with the already available feature showing which offerings are available on Atomic Avenue (number of listings and a price range). This data must already be in the Atomic Avenue systems because wishlists are maintained, so it would just be a matter of perhaps aggregating that data in a daily job and saving it out to a table - accessible by comicbase.
