I consider fixing this a major goal that absolutely has to be achieved 
before the next official release (4.2).

It shouldn't be strictly associated to any visible entity, but rather 
switchable from inside gnuplot.  I.e., we need the effect of 'load' and 
'save' commands (but including saving of entire multi-plots), without 
relying on external files.  Each "package of globals" has to be come a 
selectable global state (--> 'set' command), roughly like this:

	set state 5 to current
	# do something else
	set state to 5 ; replot multi
	# or even temporily:
	replot multi 5
