I talked with Hans about this on IRC, but for the records:

  1. performButtonClick: is something I would like to deprecate.
  2. Binding to returnArgument:«arguments» should allow for any  
binding property to end up in the event info.
  3. Long-term it should be possible to observe just the binding  
property w/o having to involve action methods: http://lists.macromates.com/textmate/2008-August/026309.html 
  -- there is a (minor?) challenge here though indicating which (root)  
object to observe.
  4. Long-term we also plan to add a sort of a filter key-path  
argument to tm_dialog that makes it so that only the given key-path is  
returned (rather than full model).
