Nice, looking good. Thank you. Making good progress.
I can now drag-drop a color from one panel to another.
In Morphic the layout would then be responsible for
determining at which position in the submorph collection
this would be added. In morphic that is done with
LayoutPolicy>>indexForInserting: aMorph at: aPoint in: someMorph
"Return the insertion index based on the layout strategy defined for
some morph. Used for drop insertion."
^1 "front-most"
which is only overridden in TableLayout.
Is that a separate responsibility in Bloc or is that part
of the responsibility of a LayoutStrategy
(or even an EventListener)?
