I plan on having a thread up by the end of the day with all the new features.
In short, within one thread, you can hit the

button on multiple posts. It turns orange each time

. You can hit the organge icon to deselect or remove that one from being quoted.
Then on the final quote you want to include, hit the regular quote button:

.
It will automatically add all the quotes at once for you into your post.
However, I strongly suggest that once you quote anything, you remove extranneous text that you aren't quoting as long as the quote still make sense. When you to that, it's best to put ellipses (...) before or after deleted text.
ALSO, now when you hit the quote buttons to quote a post, the user name AND the post are part of the quote. If you hover over the quote graphic, you will see it is clickable and it will take you to the quoted post.
