When viewing [Leeds and Liverpool Canal ? Main Line ? Liverpool to Wigan ] the gazetteer is shown as a strip on the RHS of the page. It used to be shown spread across the page which looked better as it contains more info than a standard page strip.
Did it? I can't remember
Yes it did. If you have a look at the gazetteer strip, waterways have the [Extra information] text while places don't.
So it sounds like a bug in the new layout.
If it's a bug I'll raise it.
