Marciano, thanks for the reply!
What I wanted ideally
is to have a kind of a structured display of the tex files involved, a "build view", as in winedt (see http://dl.dropbox.com/u/1021226/ScreenClip.png
As you can see, The chap numbers are different than their order, and that's because I've changed their place a couple of times. I guess this is harder to implement, so I would settle for an unstructured, unordered view of the tex files involved. But only them. Not tex files that are no more included, obsolete etc.
Do you think this can be done with ST2?
thanks very much!
