Add something to tell if action was backward or forward in listen function

[tholander]

I'm trying to make breadcrumbs for an app, and wanted to distinguish goBack and goForward by the value of action parameter. But any call to go function returns a POP action.
Is it possible to add something in the listen function to distinguish if whether it's a goBack or goForward ?

The browser doesn't tell us whether the back or forward buttons were clicked, only that a POP happened. You can probably try doing something like saving some extra location state on each navigation with a counter, and then comparing the counter whenever you get a POP. But we don't have any plans to support something like that in core yet. It's definitely an interesting feature request though.
