Sounds like a good plan - hooks for datastores or even data types along with event hooks would also be good, but not as key. Being able to place arbitrary notes on characters/items/objects would be good (For example - I'd like to say this NPC is a ranger, and someday you may add classes, but arbitrary notes would be also just as good) This is where my mind goes - If this acted like a very thin layer that integrated with the plentiful amount of DM tools that already existed, and brought the context info with it, it would be a very powerful tool to centralize all this info. For example, I create a dungeon, the name generated either by your tool or by an API call to an existing service that parses and passes data into your system, then another hook generates a map and saves the persistent url/hash/some identifier into a custom field on that object. If done right, there could be a minimal but flexible API with purely client side hooks that the community could leverage to bring more features - off loading a lot of work without needing to opensource it. Of course, having said all that, even just as it is right now is super useful and exciting and I likely will use it even without any of those things!
