Make it possible Session and Terminal displayed at the same time

Some sessions have a slide shows which are displayed on Session tab. In slide there is offten displayed some command to execute in terminal. It is little bit difficult to have a Session and Terminal tab displayed at the same time. So I often start program Terminal to execute some commands displayed in slides.

It would be nice if interface could be dynamically changed, like changing tabls to windows and vice versa. For example when I type in commands in Terminal I don't need Chatroom. So clicking on Terminal tab and drag-and-drop the tab to Chatroom window should place Chatroom window into a tab and Terminal tab into the previous place of Chatroom window.

I know this is hard to implement, but this would be outstanding, to have on screen exactly those windows that are needed at particular time.
