One thing that has always bugged me about my phone is that all of my notifications for apps (i.e. new email, sports score update, weather alert, etc.) are all out of my control. I can't control the LED color and I can't control the sound that goes off when they fire. It seems impractical to me that every notification is treated exactly the same.
I recently downloaded SMS popup, which is amazing. It lets me customize notifications for my contacts. It'd be awesome if there was an app that allowed me to manage my app notifications like this. Does anyone know of something?
