Keyboard vibration and multiwindows drawer

[al404]

Just got my pro 8.4 and can't find how to enable vibration feedback on samsung keyboard.

The other thing I noticed is that I often open multiwindows drawer scrolling or touching the right side.
Can I disable or change the way I open this panel?
On note 3 long press back button enabled or disable multiwindows drawer, it doesn't seem to work here

I've never had an issue with opening the multiwindow app drawer by accident. The keyboard settings should be in the input.
