This was touched on before about mouseover description of the op. But what if you put your mouse over the "Last reply" or "Thread subject" and had the first 2 or 3 lines of the Last Reply shown?
It would minimize constantly openeing the thread and then scrolling all over the place to find the last post, eliminating a lot of navigation imo. On average most replies are a few lines anyway and in NSG the're usually like 2 or 3 words.
Just throwin it out there. I'm a raging newbosaurus here so so bear with me. idk, the coding would probably be a nightmare. Btw the thread preview is a great editon!!!
