Is there a way of doing this in the standard system?  (I can't see this from reading the labyrinthine project enter code, but I could be missing something ;-) ).  Anyone have a changeset to do the same?

Interesting question. Karl's suggestion of using a shared flap is probably
the quickest expedient. But more generally:

MorphicProject and MVCProject would need to handle this differently as would
(the regrettably yet to be implemented) SeasideProject, AidaProject, and
CuisMorphic3Project. So the concept would make sense within a given species
of Project.

For MVC it would presumably be a matter of adding a new View for the given
Model in all of the projects of type MVCProject. For Morphic, it is probably
a matter of inserting the actual Morph into the morph hierarchy for all
projects of type MorphicProject. In either case, these would need to be
top level windows, so the insertion logic is probably not too hard to figure
out.

I guess you would want some window menu option to make the window sticky
in all projects, or to remove it from all other projects except the currently
active one. Also a visual indicator that the window has been pinned to all
relevant projects.

It is probably also possible to make the window be migratory (Eliot's
suggestion of having it be reopened in the currently active project,
whatever that might happen to be). However, as a practical matter that
probably would need to be limited to moving from one project to another
of the same type, unless of course we do a more complete implementation
of ToolBuilder for all windows of interest.

This would make a great project for somebody to try. Part concept, part
requirements, part design, part implementation, and none of it too huge
in scope. Any takers?
