Description

Sometimes I miss a stream-live notification, like if I've stepped away from the computer. A useful feature would be a "Notifications" button/dropdown around the top right of the main window, which could replace or combine with the "Account/Profile" button, (the "Sign out" and "Show access token" buttons could be links at the bottom edge of this popup).

When clicked, a dropdown overlay would pop up, extending beneath it, showing a column of recent stream-live alerts in descending order, either as thumbnails or even merely a text-only list if necessary (stream thumbnails would be nice, but not crucial).

This would enable one being able to see at any time past stream-live alerts that have fired, whether they were missed or merely as a reference for easily jumping into a stream, since sometimes one may not be ready to join a newly-live stream, especially since many streams have ~5 minute intro loading screens.

Currently, if one misses an alert or doesn't click in the window it's displayed, the user must resort to remembering that the channel went live and then have to manually search for the channel/stream.
