I know that the API is probably a ways away (I think at the first expansion) but I would really like to get features and a potential look and feel that I can begin architecting, then fit to specs later. For now, please just throw out anything and everything you would like to see, and I can then try to implement the most wanted features first. Since the API is completely unknown right now, some features may be very easy to implement while others are impossible. If there are any particular features you would want or not want, please let me know. I am pretty familiar with MRP from WoW, and was planning on somewhat modeling it around that.
However, in order to get started on it as soon as any details about the plugin API is announced, I would like to know what the RP community on FFXIV would like. There is not an addon API right now, but as soon as they release it I want to make a (hopefully) standardized RP addon for the RP community, similar to WoW's MyRolePlay (MRP). I really want to make some helpful tools and future addons for the RP community. I am a programmer/software engineer and also a RPer.
