Quality of life
Any and all concepts that improve "quality of life" or enjoyment of any title but does not affect game balance and aren't subjective (e.g. minimap does not belong here).
For example, filters in long lists of items are clearly quality of life feature regardless who you ask, while minimap is subjective quality of life improvement that also impacts game balance (navigation is made trivial). The former belongs here while the latter does not.
