The list box that shows the extensions associated with a file type has become very small and hard to handle. By now it is only one single row so that you can only see one extension at a time. And the box has a very tiny scroll handler. Both makes it very hard to get an overview of the used extensions. Grabbing and positioning the tiny handler is nearly impossible and by using the mouse wheel the entries fly by. Please make the list box bigger again, so that it shows at least three rows. It should at least have the height of the icon button. I'm using KDE SC 4.12.3 (siduction). And as I don't know if that is a gui bug or an intended "feature" I mark this as wishlist. Reproducible: Always
I updated to KDE SC 4.12.4 but the problem persists. But I have just seen systemsettings is still on version 4.11.8 - maybe that's the problem?
Sorry, seems to be a qtcurve issue.
