that's possible, when you can more you can less (or differently)

yes, this is a possible extension, it is also possible to create a new
types of objects that fits your needs that are neither slots nor
portlets but that are contained inside cells.

why not create a portlet that does what you want? the main formal
difference between slots and portlets is that slots are inner nodes
(physically or virtually contain other objects) and that portlets are
node leaves (must render some data).

here is the actual base classes:
http://svn.nuxeo.org/trac/pub/file/z3lab/cpsskins/branches/jmo-perspectives/elements/__init__.py

this is important for the theme editor.

if the new type of object that you are thinking of work like an inner
node, then it's a slot otherwise it's a portlet.


basically if the "slot" that you're thinking about contains portlets
then it's a sort of slot not a sort of portlet.

yes, any term, "boxes" are not OK, since they refer to the portlet's
display (view) with the frame and the decorations but any term that is
understood by users / developers is ok.
