Part of the reason I upgraded to El Capitan was in hopes for a snapping feature similar to Window’s. Unfortunately what I got was a green button that makes it imposible to resize open windows quickly. I also lost my ability to minimize windows that I made full screen. This app fixes all of the issues I was having and more. It is super easy to customize every detail, down to the color of your pre-sized window overlay. I also really like the ability to easily assign keyboard shortcuts to the window sizes. I don’t arrange my windows into vertical thirds very often, but when I do I’ll have 3 intuitive keyboard shortcuts to use instead of the drag-and-snap feature. Well done!
