I am using KDE's default single-click. I enabled the "automatically select icons" from the Mouse page of the control center. So now, if I leave my mouse cursor on an item, it gets highlighted after some time.

Unfortunately, it works but breaks a kind of visual feedback. Now, for example, another folder in kmail gets highlighted although the messages I am reading are from the first folder.

The problem is that I have very little hint that the right folder is selected. I used to rely on the highlighting but it does not provide the right feedback anymore.

I suggest to simply disable the "select after a while" feature of the KListView for the kmail folders, to keep the binding 'highlighted folder' - 'current folder'. The feature was introduce mainly for file management and I don't think it makes sense in kmail's usage pattern.
