What I really liked is that JEA can easily be adapted for other situations / business, like car sales, boat sales to mention a few.
I think that it could offer a bit more flexibility in the output layout of the component without having to create an override, like the ability to show only the type / city / main picture and price of the property. The possibility to show properties in columns would also be nice. But since this is beta 0.7 I believe that this kind of improvement will come in future versions. I would say the same for the Emphasis module.
Congratulations for the great work Philip. As soon as I have finished my translation I will send you the files. I think this is the least I can do to help your development.
