I agree with this. The thread title column should be a lot wider. And maybe relocate the right column information to the footer, or just remove it completely.
Since I was also a bit anoyed by the new very compact layout, I made a very small chrome extension to "fix" the problem and make the forum utialize the entire screen. I posted it the the chrome extension store for all to add for free. This will atleast work until Magento imporves the layout a bit :-).
I'm having an issue with forum width. When I make a new post, it shows up as a box. I've tried making the width smaller, but that doesn't seem to work. The only way I can get it to go all the way across is by using the "Wider" option under "Options". However, this causes another problem: when there are many posts in a row (like when I'm using a template), they all fit into one big box at the top of the page.
