This addon adds a few things that I felt were missing from XenForo's PWA app:

• If the user that is installing the PWA app is logged in, auto-log them into the PWA app (don't need to force users to log-in from scratch when they first load the installed app).
• Use Sec-Fetch-Site header as replacement for CSRF with a fallback to CSRF if browser doesn't support Sec-Fetch-Site (prevent stale sessions from causing security error message)
• Automatic refresh of badge counters when app is loaded/brought to front (this also applies to the site when being used in a normal browser)
• Give more prominent push notification permission message when initially loading app (see screenshot for example)
• Allow editing of of web app manifest JSON
• Added ability to send push notices to users (Admin -> Communications -> Push users)
• Adds option to enable debugging logging for things related to push notifications
• Does some individually small things to try and keep push subscription records from being lost
