Please make the setting for "Synchronized Browsing" an option which is stored respective remembered on a per session base. IMHO a triple option would be most useful: Synchronized Browsing On/Synchronized Browsing Off/Remember Last State.
For users maintaining different live servers, some with CMS and some not, this would save a lot of klicks.
I believe it was already on the feature list once, wasn't it? I remember having posted the same request back when the forum still ran with unregistered users.
