I love all the concept that you have, I really do.
You can see it from my lifetime licence choice too.
However, after the test , there are too many things that don't work as I thought.
The reasons for the refund are :
1.Meta Box Builder is still a bugfull and you know it too.
We can only wait for the next update for the things that we report.
No way to fix it ourselves since we still rely on the plugin.
2.That make it clear that this is not for me that still need the faster workflow.
What can you do to make me change my mind.
1. How to export data and generate XML feed from Custom Table.
