its not an urgent request as I implemented that feature already. However, I am not a good prgrammer and I would like to have this feature included by more skilled programmers.
Basically our GUI shows the data table as shown in the attached image. Now you can open quite a lot of floating windows and subwindows to work on the data. See second attachment. As this is sometimes confusing, we allow to dock/undock the windows on the left or right side of the table, depending on the relative position while clicking the dock button.
