We are making improvements to the new virtual keyboard, mostly to deal with issues with unicode characters. I’ll make sure we address your other issues.
The virtual keyboard is hidden when any control needing keyboard loses focus.
The edit area does not automatically slide; you get an event (OnVirtualKeyboardShown) with the area of the screen covered and have to move the control into view yourself at the moment.
It looks like you need to use an AutoCompleteTextView for autocompletion (see here: https://developer.android.com/training/keyboard-input/style.html). You can do something like this yourself with the new keyboard by responding to OnTextChanged to show your own dropdown list.
