If a user signs up for muliple events and wants a quick overview of all events that she/he has signed up for, it would be useful to have a "all my upcoming events" page builder section showing a list with events for that specific user, based on the email adress that the user is logged in with, matching the email address on the event registrations. It could possibly be made as a custom option on the Events List page builder block, to allow filtering the list "show only events that the logged-in user is registered for". If the user is not logged in, a "login to see your events" message could be displayed.
