Looking at all those red exclamation marks, it looks like
there is still much to do.
Not documenting dozens of Announcement subclasses, ok, but
RubTextComposer has many many instvars.
RubParagraph has nearly 100 methods
RubTextEditor has over 200 methods.
(These are only some examples of classes that look important).
This is a whole new Text/Editor/Model-Framework with up to no
documentation.
The example widgets look great, and maybe Rubric is a good and easy to learn
framework, but seriously, we should do better.
