Changing the width of a stack

Looks like setting the width doesn't keep the horizontal position.

A couple options, store the location of the button too, then position it at
the left of the card after resize, and hide any other controls that were
already on that left side.
On restore, reset the width, and move the button back.

Heres a quicky script (that I placed in a center button for testing) that
toggles between the two states.

local sWidth,sToggle, sStartLoc
on mouseUp
   if sToggle is empty then put false into sToggle
   put not sToggle into sToggle
   switch sToggle
      case true
         lock screen
         put the width of this stack into sWidth
         put the loc of me into sStartLoc
         set the width of this stack to the width of me
         set the visible of button 1 to false
         set the visible of button 3 to false
         set the left of me to the left of this card
         unlock screen
         break

      case false
         lock screen
         set the width of this stack to sWidth
         set the visible of button 1 to true
         set the visible of button 3 to true
         set the loc of me to sStartLoc
         unlock screen
         break
   end switch
end mouseUp
