An option to have events post the latest times to earliest would be amazing. This would prevent users from having to scroll to the top of a channel to select the earlier times. For servers that have channels for everyday with multiple sign ups a day, having them auto post early to late can be a hassle.
Do you mean the order the RSVP messages get posted to discord? Those post at the time of event creation; Trying to delete & repost things to get them in "the right order" would be unmanageable. If you just mean the order of the list from the /list command, then having a custom sort option would be nice, yeah.
