Here are two lines to add to latex/views.py to add tooltips in the outline to the buttons for showing tables and graphics :
# additional toolbar buttons
btn_graphics = gtk.ToggleToolButton()
btn_graphics.set_icon_widget(gtk.image_new_from_file(find_resource("icons/tree_includegraphics.png")))
btn_graphics.set_tooltip_text("Show graphics")
self._toolbar.insert(btn_graphics, -1)
btn_tables = gtk.ToggleToolButton()
btn_tables.set_icon_widget(gtk.image_new_from_file(find_resource("icons/tree_table.png")))
btn_tables.set_tooltip_text("Show tables")
self._toolbar.insert(btn_tables, -1)
instead of
# additional toolbar buttons
btn_graphics = gtk.ToggleToolButton()
btn_graphics.set_icon_widget(gtk.image_new_from_file(find_resource("icons/tree_includegraphics.png")))
self._toolbar.insert(btn_graphics, -1)
btn_tables = gtk.ToggleToolButton()
btn_tables.set_icon_widget(gtk.image_new_from_file(find_resource("icons/tree_table.png")))
self._toolbar.insert(btn_tables, -1)
