If you use a responsive theme, the flags seem to disappear on smaller devices' screens, because the bar's width doesn't adapt. So sometimes you see the flags, sometimes you don't...
Does exactly what it's supposed to do. Perfectly simple.
Many thanks to Meloniq, this is exactly what I have been looking for. It is easy and simple, and very importantly, it does not conflict with other plugins! WebTechGlobal gave only two stars. OMG! As the developer stated it is only for you to add the flags, and language translation is another matter all together.
