Need to be able to do more with "After submit…"

This is vary frustrating that the “After submit…” does not give the option to style or redirect to a different page out of the box.

I was able talk my client out of it being a deal breaker by promising I’d bring this to the developers attention.

NOBODY is going to notice the “Check your inbox or spam folder now to confirm your subscription.” when the page refreshes and its doesn’t stand out. She wanted at least a pop-up box alerting them that their info was received.

Yes, I have read the other threads about removing it, but this is I’m sure affecting confirmation rates and really is an issue.
