    I added to category of elements an argument for why ElEl preserves colimits.

    I removed the claim that the projection El(F) -> C is surjective on objects, which is not true if some F(c) is empty. There is still a paragraph about the projection not being full. This is correct but maybe a bit unnecessary, it seems clear that for elements (c, x) and (c’, x’), not every map c -> c’ takes x to x’.
