Thanks for the suggestions and feedback -- it's helpful.
#1 Will be coming in the future to the mobile apps (iPhone and
Android). Maybe in 2011, we'll see.
#2 We'll think about how to make the web site friendlier to the usage
pattern you describe. When we redesigned it to use a more efficient
AJAX approach, all the links were internalized. Perhaps we should let
the user ask for a version of the index that does not use the internal
frames layout. If the non-frames layout were available, talks would
open in another window or tab, and the talks would show up in the
browser history so your browser's back button would work.
#3 We had originally posted STPJS as a PDF-only document, but then we
created an HTML version as well (which is what comes up by default
currently, but in a separate window, not fully integrated with the
rest of the site). We've been putting so much effort into the mobile
apps that we didn't get STPJS integrated quite as nicely as the other
materials. We are planning to integrate STPJS like the conference
talks and Journal of Discourses. Look for that soon.
