I don't understand what requirements you mean. The arrangment and extent 
of all the forms should be up to the user, so that docksites and 
dockable forms should not impose limits that prevent the user from 
constructing his intended layout.

The EasyDockMaster saved layout includes only actually docked forms, the 
other forms have to be managed by the application. In the IDE case we 
can agree about a common handling for *all* currently open forms, in the 
IDEDockMaster or IDELayout. Then the IDELayout/DockMaster manager can 
store information about *all* currently open forms in the layout file, 
and on a layout restore it can delegate their handling to either the 
application (IDE) or to the EasyDockMaster. For this handling we'll have 
to define the hooks in the IDE, for the restoration of the not-docked 
forms. Currently it's unclear to me, how the FormCreators and 
SimpleLayout etc. classes/objects have to be used.


BTW, I just noticed that on Linux (KDE) the "Show single button in 
TaskBar" option has the strange effect, that on a Minimze of the MainBar 
*only* the MainBar is minimized, all other windows stay visible.
