It doesn't matter how you look at it, editing is a BIG job. Any little tricks to help make things flow are always handy to have.
Here is just one of the many tricks that I employ when editing both my own and clients' writing, giving me a way to examine story flow.
The Top-and-Tail Edit

This particular idea is highly effective with the development of the cliff-hanger endings.
