That is one of the worst responses I've ever heard. How about giving a reason why it's gone? The fact that you suggest submitting it as an idea means you might consider reinstating it, so why did you remove it in the first place??!!
I have to submit something that was a great feature, and one of my top reasons why I used spotify, as an idea? Why did you (they) remove the label search out of all the advanced search options? I'm heartbroken now when it's gone.
