How to arrange two windows easily to left and right side? v2 This question was asked in 2012. I know that the solution is in upcoming version of OS X (fall 2015), but until then... is there any similar internal function to arrange windows in Windows-OS-like way? It is hard to believe there are not...

Thanks.
This will be a new feature for the next OS X release: El Capitan

So I would suggest: wait for El Capitan :)
