I do not see why we need that at all.
For the moment let us finish Nautilus and remove most of the StringHolder
subclasses
then after porting that to SimpleMorphic will just be switching to the correct
treeMorph
because the model will be the same in Morphic and in SM

Not only: a browser model should know not only about code but about the
current state of the tools:
which view (packages,.... buttons is selected).

Not really so far we use a good tree and this is enough

We will see.
For the moment this is not important. We should get SM cleaned and port
Polymorph on top of it
and clean the main widgets.
