I want to use Textra for SMS and Handcent for MMS, because they're both top in each class, respectively. I want to use Textra as if it were the only messaging app. Then when I want to send an MMS, I would open Handcent and sent my picture, video, ect. The problem is when I get any kind of message both apps show a popup and a notification. Textra is set as my default but I'm still getting notifications from Handcent. Can I disable notifications within Handcent and accomplish my goal?
