Showing tenths of a second on a chess clock

Some people like seeing tenths of a second on their clock when they get low on time and others do not. What do you think about a clock that allows each player to choose if they want their side of the clock to show tenths of a second when they get low on time? Some might argue this could be confusing for the two displays to show the time in a different format but this can already happen on clocks where the time starts showing tenths of a seconds for each side independently once the time drops below a certain time.
