I'm looking to remove the "Tool Box" icon in the upper right hand corner of my KDE 4 desktop, but can't find any configuration setting anywhere to do so. I'm new to KDE 4, so it's quite possible I just haven't found that setting yet.
Is there any way to remove that icon from your desktop, or is it just a permanent, unmovable part of KDE?
1) With the current Plasma design it is intended that the Toolbox is not easily removable because Plasma has a high configurability and the user always should have the possibility to get things back.
2) Still, the non-removable toolbox is a splinter in many user's eyes. So there is an ongoing discussion of how to let the user easily remove the toolbox while making sure there is always a way to "repair" a ill-configured desktop: https://forum.kde.org/viewtopic.php?f=285&t=125076
