@leocg After using the sidebar for a month, I notice that the login credential there for the chat is the same as that on the main page. In other words, if I log in once in either in sidebar or as a standalone page, the credential cookies seem to share.

It would be nice if the extensions are shared to those side bar too. In that case, we can easily customize the CSS and JS of those chat via user style and script injections.
