3. I'd like to be able to find my posts in reverse chronological order.

I bumped your account up to the "pro" level, so that you have access to reports. So go to:

QDL / My... / Reports

There are two reports already there: "Last Created" and "Last Modified". These are very useful. ;)

UPDATE: You can now also just click on any user's name, to go to that user's profile page, and at the bottom is a list of all of that user's posts (that are visible to you) in reverse chronological order. And you can even click on your own name, to see your own posts. ;)
