I would like to request (yeah, I know, along with everyone else requesting stuff) that the listing of New Posts when you click on "New Posts since last visit" look more like when you click on any forum. Also, I REALLY don't like this "RE: Billybobs new Plane" thing, it takes me to the newest post in that thread, but if I haven't read the whole thread up to that point I have to scroll all the way back to the beginning to get started. I'd much rather have the down arrow that you can click on if you want to go to the newest group if you want to.

To read the thread from the beginning, click the thread title. To read the last post in the thread click the side arrow next to the persons name that posted in that thread. To read the newest post in a thread since your last visit click the down arrow next to the thread title.

If you've clicked on the "Todays Posts" or "New posts since last visit" you don't have the options that you listed. All that you have to click on either the title of the thread (which takes you to the newest posts) or the arrow that's at the far right (which takes you to the newest post, but in a new window). See image below.
Well, I would include images, but it keeps crapping out on me when I try to upload anything.
