Version: unspecified (using KDE 4.5.3) OS: Linux Currently you have a small button in the file properties dialog that you have to click on to change the file association. Instead of using the small icon, maybe the button should say [Change...], [_ICON_ Change...] or, maybe the File Type is clickable with an ellipsis beside it and you click on the File Type or ellipsis to bring up the file type dialog. Reproducible: Didn't try Steps to Reproduce: right click on a file -> open properties -> see the small configuration button beside the file type. This was originally part of https://bugs.launchpad.net/hundredpapercuts/+bug/391626 Tested with oxygen as theme.
The symbol with a tooltip is the same as in klipper/kmail settings or (more or less) in widget settings.
