It's really helpful to have the pre-created merge fields for emails like event registration confirmation that have the event's name, date, list of registered events, etc. But it would be nice to have the option to edit these merge fields. To have the option to include the detailed breakdown of a donation during event registration in the confirmation email, or remove the start time for an event if the event is come and go for multiple days, etc. There have been multiple times I wish I was able to remove/add merge fields in an email, but doing so just prevents the email from being sent at all
