Compared to Ubuntu’s usability advances, I sometimes wonder if the people working on KDE’s desktop and application suite shouldn’t implement some kind of mandatory usability testing process before any applications under their brand name are allowed to ship releases. I am writing this as I came across this screenshot advertising the availability of turn-by-turn navigation in KDE’s Marble application (which is similar to Google Earth):
If you had just one instant to check which direction to turn to – a realistic assumption when driving a car – into which direction would you make your turn?
Slightly right, sharp right, or sharp left?
I cannot even imagine what the designer of this notification must have thought to justify that three arrows pointing in different directions were a good idea in this screen. For the next release, they should definitely use one single arrow only – pointing in the correct direction of course.
