Marco Arment, on Overcast 4.1:
Smart Resume is actually two features:
It jumps back by up to a few seconds after having been paused to
help remind you of the conversation.
It slightly adjusts resumes and seeks to fall in the silences
between spoken words when reasonably possible.
Both are subtle but noticeable benefits (my favorite kind),
especially when you’re being interrupted a lot, such as while
following turn-by-turn navigation directions.
My favorite type of feature is one that makes you think, “Why did no one think of this years ago?” This is that sort of feature.
