Guys, don't forget this is alpha. It means full of bugs and features are not complete. Features will be implemented in the same order the ToDo list in the first post is.

For 0.0.13 I'm working in a better group support. When you start Yappari you'll see the groups you are participating. I'm working on changing the subject, leave the group, stop notifications for it and see the participants list. Smileys should also make the list but I'm not sure if it'll make it (seeing them from others, not adding them).

Since you can't stop being added to a group with the original Whatsapp client I don't think Yappari can stop it either.
