It would be nice if a store owner was able to create attributes for a vendor much like they can for a product. The vendor attributes would then be displayed on the Vendor Detail page in the public store. This would allow for Multi-Vendor stores to be able to collect and display to the customers more information about the vendor without having to try and format it in the Description field that is currently available.
Some different attributes that could be created would be Street, City, State, Zip, Country, Contact Number, Email Address, etc.
