want to support the last point on here, the lack of the breadcrumb path is really painful.
when just reading topics it's not such a big deal to use the backspace, but not really user-friendly or a good UI.
And when you submit a topic, or reply to a topic, using the back buttons to get back to the specific forum you were reading, is just... not a very good idea.
I get the attempt to have a newer cleaner look, but I'd really love a way to revert to the old style of topic presentation. as it is.. I have over 50% white-space on my screen at any given time. just so much wasted real estate
