Always show language status Is there an small app to always show language status?

The ideal app changes the color/shape of cursor depending on current language.

Or it can be a float icon on top with current language.

Update: Mostly I'm working in full screen mode, usual scenario for me is type something to understand what is my current language. Always show menu bar is not so comfortable for me.
This can be done by enabling the keyboard shortcut.



Now in full screen mode there will be a pop up when you use the keyboard shortcut (cmd+space) letting you see or change the input language.



The advantage of this method is you do not have something floating on you full screen all the time, but only when you call for it.
