Description

Changes

• Contents page:
  • Updated snackbar to use localStorage instead of relying on URL parameters. This means that snackbars don't keep appearing on page reloads.
• dashboard page 3
  • Rename dashboard page 3 to "Query Topics" since we're not doing content gaps yet and updated the logos to nicer ones
  • Change layout to use Paper and Box instead of Grids
  • AI box doesn't show if discovery has never been run
  • Button is aware of whether discovery has been run or not.

How has this been tested?

• dev

Future tasks

• Save the refreshing state of the discovery button to localStorage (or some other way of tracking that the process is still ongoing) so that if the user changes tab / leaves and comes back the button still shows that it's still working...
