In the GUI, if you switch views from graph to table, or paginate through any of the views, even though the URL changes so that you can bookmark the new view, the back button does not go back through those different views as you would expect. This is due to use of replaceState instead of pushState in the JavaScript, but using pushState requires additional work on the back and forward button to behave as expected.
Started some work on this, which can be see on branch, but didn't have time to get it working:
