Full Idea
The spotlight theorist accepts the block universe, but also something in addition: a joint-carving monadic property of presentness, which is possessed by just one moment of time, and which 'moves', to be possessed by later and later times.
Clarification
The block universe is eternalism
Gist of Idea
The spotlight theorists accepts eternal time, but with a spotlight of the present moving across it

A Reaction
This seems better than the merely detached eternalist view, which seems to ignore the key phenomenon. I just can't comprehend any theory which makes the future as real as the past.
