Thanks for your post. This issue has been added to tracker.

When using synchronised browsing, I often use the back/forward buttons on my mouse (equivalent to the back/forward navigation buttons on the toolbars) to navigate my browsing history. The problem is this history navigation only happens in the active pane, in the other pane a new history entry is added and all forward navigation history is overwritten.

It would be nice if the back/forward event affected both local and remote panes during synchronised browsing.
