Created attachment 3117 adds font size select ability When text mode chosen instead of flag mode for indication current layout, font size is too small, almost invisible. Plug-in source reveals hard-coded font_sizes table which intended for panel_size conversion to font size. This table works nice for specific screen dpi, it seems. Added additional combo-box on setting page of the plug-in. One can choose text size (37%, 60% and 90% of panel height).
