These are both really useful tools, and I can see them being great to have alongside Wookie. I think for the converter tool it would be useful also to contact the team at Opera to see if they can help improve it as they've been asking the community about what they do for the future of their widgets. If we can get the conversion success rate up that would be good for them, and good for us too. The Extender also looks great for Wookie+Rave as we can retrofit lots of Widgets - including former Opera and Netvibes ones - to work with the IWC capability in Rave. I notice you've taken the previous one you'd worked on that was integrated with the old Wookie UI and built it as a completely standalone application, which is great. One possibility is for us to develop these as sub-projects within Wookie, alongside the parser lib and the signer app. For that we'd need CLAs from all the contributors (I'm assuming its yourself, Sebastian and Michael) to accept the contribution. How is IP handled at Chemnitz - are you all individual owners of your work. or is it held by TU Chemnitz? > > > > So, feel free to visit the links below and try out the tools.
