Not that we have a torrent of posts, such that you need powerful and expressive tools in order to stay on top of everything, but you have them anyways.

I added a new search term, called "threadreplyto," which lets you see posts that are part of threads created by a particular user, including those that aren't in direct reply to that user. This means that something like "threadreplyto:kaiden,-user:kaiden" will show all posts in reply to threads started by user "kaiden" (minus those written by user "kaiden").

This will be useful to see the progression of threads you've started, even if people's posts aren't in direct reply to you.

I've also added shortcuts to the "More..." section on the Shortcuts bar to demonstrate useful or interesting uses for this new term.
