When I go to change my timezone in the 'system settings/date & time' panel, I have to scroll through the list of cities to find the one matching my timezone. This is very confusing, since they are sorted alphabetically by city name. I cannot simply look for my city (say, Boston or San Francisco) since they are not listed - I must find an equivalent city in the same time zone (say, new York or Los Angeles), neither of which I am certain are there before I have located them via copious scrolling.

A much better arrangement would be either a geographically or time-zone-sorted tree, a map-based selection (click the city of your choice), or simply let me enter my chosen city (Boston) and KDE determines the correct timezone.
