1. Able to "Pin on top" favorite contacts
2. More colors of bubbles, light colors .
3. In conversation, Able to edit background, "white background" to specific contacts . Not in theme but only to conversation .
4. Privacy - Able to "Private" specific contacts, with pattern or number password .

Hope you notice my idea. And I hope, you'll do it . It will help a lot for us, 'users' . Especially the "Pin on top" Wish that my ideas will help, and be an additional to improve your application .

And thank you for making this application.
