isHUD -- A HUD for multilingual users.
If you use multiple input sources, usually you have to look at the upper-right corner of the screen to check which input source is in use. With the full screen mode of OS X, to check the current input source is not as easy as just move your eyes.
isHUD will help you out. It tells you which input source is in use, keeps your eyes on the center area of the screen, and your hands on the keyboard.
Now, just concentrate on your work.
With isHUD you can:
* Double-strike the Fn key to check the current input source (Command/Option can be assigned for this function as well.)
* Use one key as the shortcut to select the next input source
What's New in Version 1.3
* When multiple displays are attached, the HUD goes to the active screen.
* Retina display support.
* Minor bug fixes
