If you think one-click input language switching is nothing, think again. For those work in a multi-lingual environment, the accumulated amount of time saved is huge, not to mention the responsive popup.

Simplifies something that drives me crazy. It's especially good for Japanese which has 3-4 different language inputs that tend to crowd up input sources…Now Switching between Japanese, Korean and English isn't so much of a hassle.

This is way better than the language switcher built in to OS X which always feels like it's non-responsive. It should be super obvious - which this app does.

I've been using karabiner indepth including input change ( using right command only), but after the OS update, karabiner failed out. still not working right now around 2016/ 11/ 14.it was too clunky to press CMD-Space every time I want to change input type.1. this app work perfectly with specified single press. (among of left option, left command, right command and right option)2. also you can check current input type by double tapping modifier Key twice. (among of left option, left command, right command, right option and function key)3. Plus it provide visual alert of input changes in the middle of the screen Every Time, even if input source are automatically changing.p.s. you should set 'select next input source in input menu' in keyboard setting as current macOS Sierra default 'Control + space'worth 0.99﹩
