I fully understand its purpose. I just figured it would be nice to remove it for people who are familiar with your works, and who frequent the forums.
Perhaps you should include an option in the control panel to remove it for users who want to do so? That would make everyone happy.
I am fairly proficient at CSS. If you want, I can see if I can do something to make the sidebar integrate more smoothly. In fact, I'll do it right now. If I can, I'll let you know, and if you like it, then we've got a fix.
EDIT: I made a fix to the sidebar. Here is a live example
. If you like it, go bug Steve about adding TechnoGuyRob's sidebar fix (I sent him a PM about it). ;-)
