New Gmail Feature

I just noticed a new feature in my Gmail. (Well, maybe it’s been around for a while, but I just noticed it!) When you want to select all the conversations within your inbox or under a particular label, you now have the option to select ALL the conversations, not just those on the first page. That way you can perform actions (such as mark as read, delete, etc.) on all the messages, instead of having to do it page by page. This is great for me, someone who uses the "archive" button quite a bit, preferring to delay any sort of email management until hundreds of messages have accumulated! Wow, what else have I missed in Gmail lately? I had better go find out!
