Is it possible to prevent windows from being placed or moved under/over a panel such as lxpanel?
This is sufficient to create a panel appearance I'm used to: Style panel Sticky, !Title, HandleWidth 0, BorderWidth 0 however, it's behavior feels unusual after so many years of using other gui's that don't allow manually moving a window under/over the panel. Also, I have been unsuccessful in preventing new windows from being placed where the panel is. By using placement penalties, most of the time the windows are placed elsewhere; however, there are side effects with each of the options I tried, and some applications, like Firefox, don't behave properly when starting up restoring multiple windows.
