My last remark for now is that it is dificult to locate a post once you have posted in it yourself. Like when I wanted to add this statement to this thread it took me several minutes to locate it, since it does not come up when I use the new posts options.
I was just about to bring this up. myself. Before this change, the topics when searching for "new posts", stayed until you closed the browser or marked them all read. This made it very easy to return to a topic you had previously looked at, in case you thought of something to add or such. Now they disappear as soon as you have opened the topic up.
I have to say that I liked the old way more.Though... maybe... make it selectable which one one wants to have?
