As you can guess by the name, the D20 tools is a web application for managing your characters, and hopefully much more as time goes on. Although it is currently at best an Alpha version, it provides a way to create and store your character sheets, all data by default is stored on your web browser using the latest html5 local storage techniques.
Currently we are only trialling the Dungeons and Dragons 4th Edition character sheet, but we are also planning to add many other character sheets such as Starwars Saga. The current features and up and coming features can be found on the Features Page.
Although the system is now live it still has a few bugs and small amounts of missing or placeholder functionality, but this will all be enabled or fixed soon enough.
Please give us feedback so we can improve the system, and we will be in touch shortly with the next update.
