PdfTeX now has the SyncTeX mechanism for forward and backward searching between .tex source and .dvi/.pdf output. Unlike source specials, it relies on an additional .synctex file to provide the cross referencing.
1) It would be most helpful if TeXify, when running in 'clean' mode, would output the .synctex file (if generated) as well as the .dvi/.pdf file.
2) It would be handy (though it's obviously not a big deal) if TeXify had a dedicated switch for SyncTeX, as it currently does for source specials. I don't know if that would make (1) any easier to implement or not.
