Instead of getting an error when you add a record and forget to add the dot at the end of it, it should automatically add the dot if it's missing and would be added successfully with the ending dot.
Less friction = better. Maybe a message that lets the user know. Seriously, this is really about good design vs idealism. Idealism says "let's educate the user". Good design says "let's make the user's life easier".
Example: I was already aware of the '.', but left it out as I was rushing through setting up DNS for multiple domains. I didn't need to be "better informed".
We discussed this at the office and thought it would be a good idea to give the error so that customers can be better informed of how the DNS records are constructed, instead of doing an automatic fix in the backend.
But its a great a suggestion.
