more options for people who used LED and now it is gone
I've noticed a lot of apps that are trying to add features to counteract lack of being able to change LED colour for alerts and phones getting rid of LED notification light entirely. there is an app called noled that has a tiny icon that floats on your lockscreen and links to the app. it only goes to app not contact so you could one up that and have the icon that was chosen for a contact be what appears. so if you have messages from multiple contacts you'd have multiple icons appear but on the screen area where there is more room, not just in notification bar.
maybe allow colouring of the icons so one can be reused for more contacts and still tell them apart? ie red heart, green heart?
