Hi Phillippe,
Yes, we are still developing Nodal, the main current efforts are keeping up to date with OS changes (particularly from Apple) to ensure a high-quality user experience.
I know people would like more regular updates, feature enhancements, etc. The difficulty for us is that we don't have a large enough user base to fund a developer full time, so we have to wait until we have sufficient sales to fund a development sprint, and the software developer has to be available at the same time. This limits the pace at which we can release updates.
We have looked at other possibilities, like making the software open-source. However the cross-platform build procedure is quite complex and the licensing code would need to be disentangled in an open-source version.
Regards,
Jon
