  • Raw and function symbols can now easily be specified in the JSON
  • Symbol groups (for autogeneration of the on-screen keyboard)

  • Configuration of cursor behaviour in a blank field
  • Configuration of blank editor text

  • Many more tests (100% coverage of checked functions)

More application development using guppy is slated before it will be considered ready for a full release.
