1. "Back" system button now acts as most of Android users expect: navigation, in reverse chronological order, through the history of screens the user has recently worked with. See https://developer.android.com/design/patterns/navigation.html Return to the Default timeline clears the whole history stack, so when a User presses "Back" button on the Default timeline, he/she leaves AndStatus (and returns usually to the Home screen of the Device). #253
2. Share a message with its attachment.
   "Share" message context menu item shares not only textual part of the message, as before, but the attached image also. This way a message with an attachment can be shared from one Social Network to another within AndStatus, or to some note taking application, e.g. to Omni Notes, where it will be stored with the attachment. Some file managers, e.g. Total Commander, allow to save shared attachment to a file. #387
3. Added "Overflow" button to the row of buttons below each message: to open message context menu. This button may help new users to notice existence of the context menu. It also may be used in a case you set "Long click to open context menu" option in Settings -> Gestures. #332.
   Clickable areas of these buttons made larger and wider to ease tapping the buttons. #410.
4. Styles of the Navigation drawer changed to make drawer items easier visible.
