A more Powerfull Event Module
Suggestions
I can't actually see in your attachments what your suggested improvements are - they are too blurred, but a lot of what you suggest in writing is doable now by using Jamroom's Form Designer tool and additional modules. For instance, I use the UltraJam Google Maps module to add venue mapping to events. Then there are the OneAll and ShareThis modules for adding things to social media. Also, don't forget the Recurring Events feature that is also built into the module and just needs enabling.
The only thing I'm not sure about at the moment is how the Jamroom FoxyCart or PayPal modules could be utilised to sell tickets - its not something I've tried before.
