It's wrong to complain without offering a solution too so...
I'd like that feature too but didn't ask. Seems like customer requests are an interruption. In customer service, the easiest way to be blunt is to say "thanks, we'll add that idea for future consideration."
Bear in mind in the earlier response (Nov 2007) you stated the feature would be available in 1 month, 3.5 months after that it's a no.
Every business has priorities - most make attracting and retaining customers #1!
"No response required"
