Seems so. At least I can grap a docked window (e.g. Messages) and move 
it to another part of the main window or make it float :)

Anchor docking seems to work better than EasyDockTree currently. I 
tested that one at first, but I had problems to get the "windows" to the 
positions I wanted them and to keep them there (especially when saving 
and reloading a layout). With anchor docking I haven't experienced that 

But the following problem appeared:
I had docked the object inspector into the docked code explorer (thus 
creating a page control containing the two) and saved that layout. I 
then restarted the IDE which used the default layout (worked) and then 
loaded my saved layout. I then got a "loop detected" error somewhere 
when creating the object inspector, the code explorer or the area of the 
page control (I don't know the reason exactly, cause I haven't done 
extensive tests on this topic yet).
