Konqueror can manage a divided window (as kwrite etc. can also do that). As Konqueror is not only a browser but also a full operable manager of files tree, it is possible to have a part of the divided window used as browser and the second part as file explorer. Or are more operations being not browser operations possible (I would especially like to edit HTML sources of files in the one half window of konqueror and show the result in the second half of the konqueror window)?
if possible, how to do that (I don't understand well the last item in chapter 3 of the Konqueror manual)?
