Move the text to the Activities overview (option)

[forteller]

Hi again.

The very useful thing about this extension is that it keeps you reminded of your next event. But having the reminder in your face at all times might not be the best option for everyone. I think a lot of people might only need that reminder from time to time, like for example when they open the Activities overview. Moving the text there, either by default or as an option, could be very nice for some people.

I've tried to make a simple mockup of how this could look here: https://gitlab.gnome.org/Teams/Design/whiteboards/-/issues/16#note_1325532

Thanks again for your work! :)
