Move icons to fit within Dynamic grid upon resize.

If the dynamic grid is made smaller, currently icons will simply be
hidden from view. Instead, create extra screens and squeeze the icons in
so that they will all be visible upon resize.

In some cases, icons can end up creating screens when it's not necessary
we should revisit this at a later time and look into making these icons
show up in a more expected place.
