Congratulations on getting the new Kepler menu layout working (and
the ability to change the configuration)!
However, it looks likes we left out a couple of menu items that I
just recently learned to appreciate! --- namely 'Instantiate Attribute'
and 'Instantiate Entity' under the 'Graph' menu.
I must admit that I did not understand just what these menu items were
used for until recently (and I might have suggested to Laura that we
leave them out in Kepler).
'Instantiate Attribute' allows the user to add attributes to the
workflow by name. This allows one to add attributes that are not in the
Kepler Actor Ontology tree to a workflow! (And we have not included all
the ones in Ptolemy.) Similarly, 'Instantiate Entity' allows one to add
actors; there are many Ptolemy actors/directories that we have not
included in our actor ontology and I have already been asked by several
users how to add such actors to workflows without having to recompile
the whole Kepler system. It also turns out that whole new actor classes
can be added using this menu item (i.e. new classes).
So I think these two menu items should be included in the new menu
layout, probably in the Workflow menu. Maybe Laura will want to change
the menu item names?
