Hi, I don’t know if this has already been discussed but thought I’d add it to your ideas pool.
eZ Publish offers its developers an Open Funding scheme which I could imagine would also work well within the modx community, Open Funding basicily translats into interested parties offering to sumitt part funding for the undertaking of custom modular/extension/plug-in etc developments to the core system.
So lets say you have a feature, outside of standard modx CMS which you’d like to see built, while I’m sure the core modx team would always try to cater for such demands sometimes the feature could be niche. So you post the project on a board and see if anyone else would also be interested in building a similar module. If you find such like minded people a While Paper/Spec Sheet gets written up with a list of companies willing to fund, as the project gets costed and the agreed funds get guaranteed the modx core team are paid to develop the new feature.
In this way the extension gets built quicker (as classed as paid work), cheaper for the individual parties requiring the feature (sharing cost), and as the developed modular/extension becomes available open source it extends modx repository of features.
