RocketPig is more a proof of concept than anything else, at present, meant to demonstrate the RPCore library, which provides a standardized way to maintain and share fields for roleplaying information. Things like a character's full name, a short description, and so on.
There are tweaks that still need to be made for WildStar's API revision 7, including visual cleanup to bring things more in line with the new UI designs and the conversion of RPCore to a newer-style WildStar package, but the addon is perfectly functional under the current API.
The forum thread for RocketPig and RPCore, dating back to early in Closed Beta, can be found here.
