synctex is great! and works perfectly here (back in 2003 I tried to convince Hagen and other pdftex guys to write something like that inside pdftex, to no avail. That's how pdfsync started, as an awkward workaround... happy to see it gone)
Robin, it should be easy to add support for synctec in LaTeX Watch, (just add that -syctex=1 option at the right place in your script). Would you do that in the next future?
Thanks to Jerome and all who are contributing to this feature, this is really becoming mature now.
