Hi pavel
I spent quite some time (… more days) looking at the Smalltalk ui theme and icons and
I think that it will help.
So let me give a real try and judge the result because the devils in the details.
I do not think that displayableObject should be a superclass of Model and I’m not sure
that Model should DisplayableObject should be a subclass of Model.
May be we should have a DisplayableObject and a subclass of Model.
The first step is to make sure that Presenter handle theme and icons correctly that
all the Presenter subclasses are clean. It will remove a lot of mess.
Now I would like to have also UIManager default managed in a decent way

In the standard case, it will only hold the selector for the icon, but then it may add some additional data (like information about the small progress bar embedded in the icon). In the worst case it could provide as an additional property the form for the icon but then it will limit to use such thing effectively with other UI frameworks (like HTML rendering).
