Dear All, I'd like to ask if on top of things is an idiomatic expression or not. I believe it is, but perhaps it's not. What's more, I'd like to ask if the following application of this expression is correct or not.
A: Do you know if there are any theatrical plays in the town? B: I'm not sure. Ask Kathy, she's always on top of these things.
Thank you

Yes, your example is a perfect use of what I would call an idiomatic expression, meaning "in-the-know", "knowledgeable", "up-to-date".
