Every year or so I do a search on this subject, since I am a Fantasy Grounds(FG) user and would love to use the tools that are part of FG to either be a player or GM. A few years ago I put together a few tools in FG as a proof of concept to show that even a user cool modify FG (through the MoreCore rule subset) and automate a large portion of the game. Of course this would be arduous since that person would have to manually enter the skills and spells... but it could be done. Below is a link to the video.
