Coming from Windows and Linux distros, I was used to using a tiling application with my desktop. This is a program that allows you to move windows to fill certain portions of your display with keyboard shortcuts. For example, in Windows 7+, holding down the windows key and pressing left or right will fill the left or right half of the screen with that window.
If you’re looking for this on Mac OS, check out Spectacle. It works great and it’s very customizable.
Update June 8, 2020: Spectacle is no longer supported so I have switched to Rectangle.
