(assumming you meant would not be readable):
But the customers do not use KDE to write slogans about KDE, they use KDE to do what they found useful and/or fun. Of course, there is a myriad of ways how you can be productive in KDE so you have to choose something to show. Still, writing slogans in KWrite is not one of them.
KDE users can change many things in the default setup. However, the change you made is not a likely one IMHO.
There is some misunderstanding. That's not my screenshot (you can easily see this from the history of the image).
I still cannot understand what you want to prove. If it must be absolute default, then no KWrite will start with KDE, and no "Elegantly yours" in KWrite window, and no Konversation icon on the panel, and no Bluetooth on every desktop. What if there would be KWord? Isn't changing the font size in it "unusual customization"?
If you have different vision on how KDE 4.6 should be presented, please share it, but do not claim this screenshot does not meet guidelines.
Oh, seems we have broken some ice. Good news.
The settings used need not be default. However, they should be reasonably common. It should show the desktop at work, not at startup.
KWord would be formally all right, except that openSuSE recommends and provides LibreOffice so someone else would have to translate the screen shot. I could show the same thing in Okular (now that I have tamed groff 1.20 to typeset in Polish) or in Konqueror.
Changing the font size is not unusual for KWrite, especially when you are short-sighted or something, but changing the typeface to serif is surprising. I thought it was KWord when I looked at it.
