I think a showcase of applications created using Ext would be a welcome feature linked to the Ext homepage. This would demonstrate to current/potential users what is achievable by putting it all together and, if possible, a run down of how the project was engaged, tackled, lessons learned etc,.

This is most likely to come from community sites which are public but there may be enterprise customers willing to talk about their experiences.

This would be of great assistance for people with ambitions to create small or large projects and increases potential for additional license sales.

I have come across posts with image capture fragments of what people are generating and there are some wonderful, fully fledged, real world apps being created. It would be nice to see a few different examples.
