So now it seems the sidebar is hidden until you click it's button on the top left. I'm sure a lot of people are happy about that, but I for one want the old behaviour back. I liked having the sidebar visible at all times - the bookmarked threads become highlighted when there are new messages and I use that feature to keep track of several threads that I follow. Not having them visible makes it annoying to do this because I can no longer see at a glance if there are new messages. Please make the sidebar hiding optional.
