I usually use konqueror for browsing too (it is a lot improved recently).
In the same line I placed the navigation buttons, location bar and search bar. But when I resize the window that line is splitted in two, with a loss of usable vertical space (see Figure).
I don't know why this happens, it seems that the location bar tries to be not shorter than a certain amount.
Well, that amount is much more of what needed to type in any web address!
Somebody smart knows a patch for that?
