Default Which Thread Might I Make an App Suggestion to Developers?

I would like to suggest an app to Developers. I know this is the wrong thread but I don't know the right one. I was going to suggest a live weather wallpaper app in which you could choose your own background. I love live weather wallpaper but hate the corny pictures they use as backgrounds. I'd prefer a real photo of my own area in the background for their clouds, snow etc or just show the sky and no land background at all.
