One of the original intents of 'tile' was to make it simpler to create
Tk widgets. There's quite a lot of tedious boilerplate in Tk widget
creation. See http://tktable.sourceforge.net/tile/WidgetGuide.html for
something about this. However, when 'tile' got integrated the necessary
functions were not exposed as part of the tk stubs and its currently
somewhat hidden.

Related to this -- to construct new UI's using elements you need a
reasonably general purpose element engine. I one toyed with using GDI+
so I could specify an element with, for instance, a certain gradient or
shape. Working with this leads to the obvious conclusion that it would
be great to be able to specify the look of an element using something
like SVG. (See http://tktable.sourceforge.net/tile/Gdiplus.html
and http://www.patthoyts.tk/gitweb.cgi?p=gdiplus;a=summary)

There might be more involved in making the widget functionality easy to
hook together but this would cover the look part of look and
feel. Events mostly deal with 'feel'.
