Ok thank you,
So to be clear, if I want my changes to work beyond each upgrade, I need to add a custom file?
As I am on a mac, this would be adding something like:
Doctrine2.custom.skipper.cfg.xml which would be placed in the following folder on mac: /Users/USER/Library/Application Support/Skipper/Configurations/Frameworks
The content would be:
This assumption is based on the idea that the configs are array merged...
NB: I updated this as the previous information was not accurate.
