Let us take existing open tab and create a new window
When having a tab open, let us pull the tab out of the window like a chrome browser tab, creating a new window to allow a side by side window of two sessions at the same time. Having to flip back and forth between multiple session tab's to look at something is not very productive.
The 4.7.2 version has a possibility to open terminal in a new window. Just right click on a Host and select open in a new window.
