NOTE: Due to Apple Sandbox limitations, the Apple App Store version (Command-Tab Plus ) does not support closing and hiding applications, as well as switching windows for the selected application. Some functions may be implemented in future versions, but this requires significant work.
I recommend trying the proffesiononal version of Command-Tab Plus.
Command-Tab Plus Helper
To use the hotkey Command + Tab to bring up the switch panel for the Command-Tab Plus
version which is downloaded from the Apple App Stroe, you need to download and run Command-Tab Plus Helper
