Table of contents
I've noticed when you want to read a thread and read all its posts, when its time to return back to the table of contents, there is nothing noticeable to click on and return to the main page. The trick would be to click to "answer" but instead of answering, click then on "table of contents", below and then you are back to the main page, instead of clicking on "back" a number of times.
