I want to be able to resize 2 chrome windows on my screen side by side, their widths and heights will adjust. Then I want to be able to use the windows + arrow / pg keys so that I can quickly snap them into the set position I've created.

I was able to kinda of do it using aquasnap but it wasn't reliable.

Any suggestions?

Here is a video of what I'm talking about. https://www.screencast.com/t/y8E0ke985Ys
