Explain the problem as you see it
This morning, I had two nodes opened side by side: my today node and a weekly tasks node. I wanted to open a third node in full screen mode for writing. However, to do that, I lose my today+weekly layout and can't quickly access it anymore.
Why is this a problem for you?
It just slows things down.
Suggest a solution
The easy solution is to allow a "click to open in a new window" feature. This way, I can keep my original node layout as well as visit the new node in full screen.
