It would be really helpful to be able to sort the RSVPs (in the admin on the RSVP Events screen/page where you can go back in and edit them) by the DATE OF THE EVENT. Right now you can sort it by post (event)title name or by the date it was published. For people who schedule lots of meetings or classes it would be more useful if these could be sorted by the date the event actually is.
Just a thought. :)
