It would be awesome to have a little more control on configuration of php.ini per user in their control panel via a GUI interface. Making it as highly configurable as would allow like changing openbase url, post_allows, etc. I know it has security risks invovled, but I started doing my own hosting because of the lack of control I could get out of my hosting provider.
Maybe this could be a paid plugin situation. I know I would pay for that and it could be another paid plugin to help development costs.
I thank you and keep up the great work ...
