pfSense

On the System > Advanced page's System Tunables tab, it's really hard to
a) find/check values, since they are in no particular order
b) compare the settings of two machines, because, again, the values are in no particular order.

Being able to sort them by the Tunable Name is particularly important as it seems the Description of these fields has been changed over the years, so two systems originally set up at different times with different versions of pfSense have different descriptions for the same field, making it even harder to find/compare the values.
