I wanted to write about this anyway. Unfortunately, current widget system is not
well suited for programming (in user-defined widgets). Currently widgets mostly
are "high-level" ones, that do fairly complex tasks. That was fine when all
widgets were builtin ones. But now more of a low-level, primitive widgets are
needed - that do some well defined atomic action. Good example is completion.
What is needed is probably such primitives as next-match, previous-match,
insert-match, exit-menu etc. Using these most of other tasks could be easily
porgrammed with user-defined widgets - and if some prove universally useful,
they could be implemented as builtin.

This assumes, that user-defined widgets work. As my recent example shows, not
quite :-)
