File dialog: preview widget

[Peter Penz]

Hello,

during the port of the file-dialog to KDE 4 and reading some discussions about 
the "cluttered file dialog" (http://dot.kde.org/1188928003/1188936931, 
http://www.osnews.com/comment.php?news_id=18563) I was wondering about the 
preview widget: http://enzosworld.gmxhome.de/temp/file-dialog.png

I personally never used the option to turn off the automatic preview by 
unchecking the "Automatic preview" checkbox and hence I also never needed 
the "Preview" button. If I don't want to have a preview, I just turn off the 
preview widget completely...

It is not my intention to remove any functionality that is needed, but in this 
case I could not think of a usecase where using the checkbox/button has any 
benefit against just turning off the preview.

Is there something I'm missing here? If not, I'd like to remove the checkbox 
and the preview button, as it adds quite a lot visual clutter.

Thanks!
Peter
