+Subject: [PATCH] Supporting xfce4-panel in dwm
+
+We treat the panel as special window which
+- never has borders
+- never has focus
+- always has y=0
+- is never shown as active window in the indicators
+- is shown on all tags (via config rule)
+- is ignored on focusstack (MOD+j, MOD+k)
+
+Which window? "xfce4-panel" - configurable in config.h
