+# Things missing
+
+## Color System
+
+Topics to debate.
+
+Given that we need pairs of foreground/background to be set when
+operating on a view, should we surface the values independently, or
+should we surface the attribute?
+
+Currently views hardcode the colors to Colors.Base.SOmething for
+example, perhaps these should be set with styles instead, or even
+inheriting them.
+
+The reason why the Colors definition is useful is because it comes with
+defaults that work for both color and black and white and other limited
+terminals.  Setting foreground/background independently tends to break
+the black and white scenarios.
+
+## Color and Dialogs
+
+Perhaps dialog containers need to set a general style for the child widgets,
+so that when we set a dialog, or error box, all the children added get the
+right set of default colors.
+
+Replaces `Colors.Base.Normal` with `Attributes.Normal`, and perhaps attributes
+points to the container.
+
+## Views
+
+Checkbox, ListView, Menu.
+
+Wanted:
+- Function Bar
+- ScrollView
+- Multi-line text editing
+- Radio buttons
+- DateTime widgets
+- Shell/Process?
+
+## Layout manager
+
+Unclear what to do about that right now.
+
+# Unicode
+
+Needs to move to `ustring` from `NStack.Core` to get full Unicode support.
+
+# Focus
+
+When SetFocus is called, it need to ensure that the chain up the views is
+focused as well, something that we got for free in the old Container/Widget
+model, but needs revisiting in the new model.
+
+# Bugs
+
+On the demo, press tab twice, instead of selecting Ok, the first tab
+does nothing, the second tab clears the screen.
+
+# Merge Responder into View
+
+# Make HasFocus implicitly call SetNeedsDisplay
