In response to people using low screen resolutions have trouble reading tabs, I've killed off the right sidebar completely. I moved everything to the left sidebar, accept for user account specific stuff like the 'My Profile' and 'My Favorites' links. Those links I've put in a new drop down list on the top navigation bar (with some snazzy effects). I hope this makes things easier for you guys, and if not I really want to hear your feedback. Let me know if anything is confusing.
I also killed off the Latest Transcriptions and Latest Arrangements lists in favor of the more classic lists which you should see above this post. I think most people like these lists the way they are now, so I will most likely keep them like that. As always, I await your feedback.
