Pls make it when you press the "delete all alerts" button it doesn't take you to the alerts page and just leaves you on the page you were on. No point as there all gone xd
The 'delete all alerts' is actually just a link the plugins main page which does the action.
I'm not going to modify it to do the request via AJAX, if you really care that much 'right click -> open in new tab' and it won't redirect you.
