Well, here's one thing I have found about the M9 that I don't like that all my Galaxy phones had...the ability to select custom SMS notifications for each person on your contact list. It was available on the default messaging app on all the Galaxys I had, but I can't find anywhere that you can do it on the M9. You can set custom ringtones on your contact list, but not SMS notifications.

Does someone know if that can be changed on the M9? And if not, can anyone recommend a good 3rd party messaging app to use instead of the native one that comes with the HTC phones? I'd prefer a free app, but if it's really good, I don't mind paying a couple of bucks for a messaging app that lets me do what I want.
