The KDE clock is extremely poorly designed usability wise for the user. 

Clicking configure clock yields 6 different tabs for the user of which 4 are "Plain Clock", "Digital Clock", "Analog Cloc", and "Fuzzy clock" making the clock configuration dialog way too large for its intended user. Those 4 tabs can be combine dinto 1 single tab which is simpler to use and takes less screen space. 

It could be called "Look" for example. This tab would have at the top a dropdown menu where the user can select the type of clock, digital, analog, fuzzy or plain. The options would change depending on the user's selection. This would also be more efficent because each type of look has many charachteristics in common for example, all of them have a "Show date" option, and a draw frame option.

Another problem with the clock is the timezone, no I'm not complaining because it doesen't have that nice map with the selections underneath like XEvolution, it is just that the timezone options don't fit when most are enabled and you can not scroll the menu.
