Some things I've said:
"This is working for now. If it stops working, we'll do something else."
"Thanks. I'll think about that." (Or you could say "We thought about that," or "I think about that all the time.")
Mostly people want to know you heard what they said, and that you have thought about what they're suggesting. It doesn't hurt to say that you have, or that you will.
