There were multiple instances where, when I clicked in the URL box, it showed a previous address, but otherwise showed the real address. A page refresh corrected that.
And there seems to sometimes be an issue when you are editing the URL and it does some wacky stuff, like it doesn't like you to edit it. So that needs to be corrected.
I would like an option to not make the query items after the ? be "breadcrumbs". One whole breadcrumb would be okay, or just plain text.
