It would be great to add a custom icon and link....for instance i have a customer who wants the profiles to link to the listing's IMDB

this could also be nice for business directory listings!

I would really like to see a function that would add social network links/icons for individual directory listings. I visualize form fields in the admin section for a particular listing. These fields would represent the major networks (g+, FB, twtr, etc). For each listing, by adding social network addresses, a small icon will appear in the listing details for that network linking to that listing's social network account.
For Example, Joe's coffee shop pays the directory host for a listing. When signing up, Joe sees he can upgrade his account. Upon upgrading, Joe can now put links to his Youtube, G+, FB, and Twitter accounts. After entering the addresses, his listing now displays the appropriate icons linking to the appropriate accounts.

this would add another possible revenue stream for the directory host.
