@ron I have made an attempt to merge the Int and Double versions of the spinner builder. At the same time it provides defaults for min/max/initialValue + the initialValue will be taken from the propertie if supplied. This also makes it possible to support Float builders, and it can more easily be bound to both IntegerProperty and ObjectProperty<Int>. If you have time, can you try it against your spinners?
