Split Editor window

[AntoineCharton]

Just one more step other VPLs for Unity don't have. There are cases in workflow of programming where we should see two (2) windows - one for reading something (help system, snippets, other scripts) and one user is working on. We do know this from text editors. I can't imaging if this can easily be done with Unity Editor. And whats about opening two Constellation-Editor-Windows?
