+
+	* kfwin.cpp, kfwin.h: The listview items show a mini-pixmap, like those
+	in kfiledialog. For now, they're static icons (only folder and document
+	icons), maybe we can show the correct icons for the mimetypes, later.
+
+	Also introduced drag-support, you can drag files from the list.
+
+	* kftabdlg.cpp: accept Key_Enter to start the search, too.
