Divisable window panes

One of the most enjoyable things about Eclipse and the family of Eclipse base IDEs is the ability to drag windows to cause them to split. There is also no limit to the amount you can split.

I know you can drag tabs out of sublime into a new window but this isn't really as useful as having the split panes in Eclipse.

It would be great if you take a look at that functionality if you havent already seen it.

Full screen + split panes for multiple files would ROCK!
