I've seen the workaround to add computed columns but it doesn't show graphically that the column is computed. Likewise, I could do the same for triggers but again I wouldn't be able to see at a glance where the triggers were. I would have thought another box like you have for default value etc would suffice. If you don't want to make an interface to build triggers fine, but at least allow us to mark that a column has update/insert/delete triggers or is computed.
