Hello, I was wondering if you were planning on creating a sidebar version of the page monitor extension.  I find that this would be extremely helpful to monitor pages, while visiting other pages.  Currently the problem is that users cannot simultaneously do this, because when they click out of the extension, it does not stay.  As a result, the user (ie, myself) has to keep clicking on the page monitor icon each time that I would like to check if a site has changed.  I don't mean to ramble, but I feel strongly about this concept and Kudos to you for creating such a great extension.
