Quick switch between Apps
Using Command + Number key you can easily switch to an app without tapping a bunch of keys.
Convenient Window Switcher
When using Command-Tab Plus, by default it displays only the icons of the apps running on the current display or space. Thus, it isolates the apps in one space and the apps in other spaces. Of course, you can disable this function in the app settings.
Hide not used Applications
Command-tab Plus hides the icons of inactive (hidden) apps. This function allows you to quickly switch between the apps you are using at the moment, which is handy if you have a lot of apps in the background, but you don’t want them to show up in the switcher.
