smoother (not rack) and prevent catching along the bottom with changes

Look at the caster installation on a rolling stand.....they retract
when you step on the stand. You will need a larger caster and heavier
springs. You want enough spring pressure to keep the end of the door
off the ground, but not so much as to bind the door as it moves.
