To ease the organization of the floating panels it's possible to connect them to the right or left of the work area, in a group of panels.
In order to move a panel, or to connect
it or to disconnect it from a group of panels,
click on the points zone 
that is next to the name of the panel, then maintain the mouse pressed
and drag the panel towards the desired position.
It is possible to show
or hide the groups of panels by clicking on the 
button.
You can also show or hide all the panels by pressing the F4 key, or through an option of the Window menu.
When you hide the panels you increase the area of the work window, this is why these options are very useful.
