- Assign pictures to your contacts.
- Notification of messages in system status bar, both audible or silent. This can be turned on/off.
- Display contacts as list or grid view.

Note: This is NOT a public chat-room app. You have to invite eachother by exchanging ID's and filling them in, in the Invite window. Only then you can see eachother in the Contacts list.
