Thread:Feedback/No way to 'bulk follow'?

In the current system I can see all the new messages in all the threads in a very quickly readable manner by just diffing the page since I last read it: All the new stuff is color highlighted with a minimum level of context. (Some context is good; but presuming that I've been following the page I don't want to see the whole thread). I can't seem to find any parallel for this in liquidthreads. Is there any way to recapture (and improve on) this really useful usage model?

Perhaps some kind of global history page for the talk page which nests the histories of all the threads then some diff-span like functionality that will show you a page with all of the new fragments, and a link at each fragment to expand it in case you need more context? (oy, the poor database servers)
