Threads updated since last visit?

Yes there is.

Once you have clicked "Mark Forums Read" once, everything you've read should be tracked accurately.

On threads in which there are new posts there is a little arrow to the left of the thread title. Click that and you will go directly to the first unread post in that thread.

Is it possible to make that the default behaviour when you click on a thread title, rather than having to hunt for the little (10 pixels?) arrow? Then it would feel like home :-)
