Turn your applications into stacks on mac
Here is a guide on how you can make your applications into stacks on your dock.
First go to your application folder, create a new folder by clicking setting icon on the finder menu.
Give a name to this folder and drag in all the files you like into this folder, and you might wonder in my screenshot below how did i change the folder icon, its easy, right click the folder and "get info" it will bring u the folder info, drag any application icon you like to the info's folder name, on top of the "sportlight comments"
Now just drag the folder into your Dock, there you go, and your applications are on stack, right click the folder on your dock change to folder instead of stack .
