Forum needs more sorting options

I was just going through some sub-forums and noticed a few things that could be added for organization/usability of the forums.

1. There is no method in the sort links at the top for sorting posts by Thread Started, ie: by date and time of the First Post. The default is organized by date/time of Last Post, but for low-activity boards like the DoH board, I'd rather add to a new discussion than one that's been bumped from days or weeks ago.

2. Speaking of Last Post sorting, there is no sort link at the top to restore sorting by Last Post short of backing out of the sub-forum and going back into it.

3. Just now when searching for other posts on forum sorting to see if there was already a post, I noticed that you can't return directly to the forum that you searched from. It's listed by the search parameters, but it doesn't give a link to go back. So after going through a few pages of posts, my only choices to return from whence I came were to go back through all of the pages I checked or return to the Forum Top and go back down to the forum I was in.

4. The sorting options at the bottom really should be added to sort-links at the top. I made this entire post without noticing them until after I posted.
