In both android notification and heads up style you allow 3 button options. I'd like to mark button 1 as not used and button 2 and button 3 as quick reply and mark as read so that my 2 options are right aligned for my right thumb. But if I leave button 1 as not used, then the 2 not null selections take the places of button 1 and button 2 essentially. I think "not used" should take up a default width to allow blank space. I realize it uses a fit layout style which is clean too, just thought this would be nice to have the buttons where I feel fit.
