• The popup is showing behind the editor bar and the sign out button is not visible

• Only 2 resource pane is able to open after load 2 resources. Because the the icon for selection / second resource section in the same resource pane (eg 3,4) is at the end of the page . Only able to see if I scroll all down till the end of first resource.

After load resource

after scroll till down

• Font selector option in the file -> font is not working . Not able to understand the use case . Expect to be set common font for all sections from a single place
