Developer website: The Tonto Project
It is the goal of this project to develop not just a better editor, but to also provide a rich, extensible platform for progamming the Pronto family of remotes. Planned features include a complete CCF developer's API, Module support for user-extensions to the Tonto user interface, online access to a database of IR codes and expert IR analysis tools for the creation of clean codes and discovery of discrete codes. A module is in development that will load TV listings from the Web and automatically build and install panels into the Pronto.
Most of the CCF developer's API is complete. The IR recording capabilities of Tonto are significantly better than ProntoEdit. Upload/Download reliability is about the same. The best way you can help is through testing and frequent feedback and suggestions.
