Documentation: better quickstart (remove class and provide a fully functional example + same form config using only classes)
Documentation: better Field Definition Modes
Handle Array objects / complex structures in Unified Mode (#197 #270) (I have some new code which partially fix the array problem but not yet fully tested and not ready to be pushed)
Implement Form Requests (fetching/creating/updating) with Promise and JSON support.
Incremental Auto Saving w/ validating before sending data to the server (with a flag to disable it on some fields).
Converters (#229)
Bind form fields values to external Model (#243)
Splitting Validators in multiple Validation Drivers packages (setting up a monorepo)
Plugins & Drivers management (enable connection of Validation Drivers to Validation Plugins).
Externalize to another (NEW-NAME) package the Form/Fields state management Core to be used outside a react environment (would be cool to support vue.js or others front end libs)
Externalize nested field handling in an optional NEW-NAME-nested-fields package.
Implement @decorators (don't know how can be used yet, it's unlikely to be a short term feature, a massive rewrite could be needed)
