Meta Box

Please provide more information on performance and MetaBox. I have found significant slow downs while using Views Is this also to be expected?

Perhaps Builder and Views are best for prototyping only - but for performant templates do we need to build custom?

Thank you.

Hello - Thank you, as always, for the great help and documentation.
I attempted to use this function for adding the featured image to a CPT added via MetaBox.
The column simply does not show if I add any value to $position =
