An awesome update would be to allow for the Scheduling of DNS Updates.
Often DNS changes need to be made at a specific date/time in the future.
This feature could live under the DNS Tab, Select “Create Scheduled Update” which launches an interface similar to the current DNS entry interface. You make the changes that are needed, then specify a Date/Time for this new version to go live.
This could be coupled with a DNS History, and the ability to view/rollback to a previous version if desired.
