For thermostats the range setting is a great way to keep comfortable. However: if you realize you want the heat a degree warmer and that degree would violate the minimum 5-degree separation between “heat to” and “cool to” you end up having to edit the “cool to” first.
The cleaner way would be to eschew the two dials altogether and let me specify a target temp on a dial and a +/- spread in a slider under it.
On the device you could do this as a two stage: one dial at to set the target, another to set the spread.
