Hello,
Welcome to BBT. I will suggest you to watch all DAS related educational video from BBT education center. That will help you to learn many DAS features.
For now.. you can right click on any widow you want to move out of DAS main window, then a window will pop up named "Frame Window Configure",
then click on the button Pop Out (Blue Circled Below) which will release the window you want to move out from the main window
Best of luck
