I second this request. I keep my internet explorer clean, with no toolbars. No favorites bar, link bar, google toolbar or such. I use lastpass constantly, and would prefer not to have it take up a complete toolbar space for a single button. I know we are asking a lot to ask you to make up for Microsoft's error in judgement since IE7 to prevent toolbars from being moved to another area of the browser. However, if this is technically possible, I would leap at the opportunity to see a lastpass button on the command bar of IE7 and IE8.
BTW, my name is David too
