Most of these are unclassified, except for TextURL's, which lives in Morphic. (This method references Morph directly, through an #isKindOf:.)
Now the name strongly suggests that the method/group of methods belongs to a graphical UI, which makes me think that Morphic is, indeed, the place for them to live.
But is it really? Could these methods live in Morphic for now, or do they really belong to a layer just below Morphic and ST80? (We see quite a few things in the image that are parts of or support for a GUI, but not any specific GUI. Transcripter, for instance. Is this layer the Graphics package?)
