@michmoor no to "commit confirm" of a candidate config. In TNSR CLI when you type exit you commit your change. Please test your changes in a lab environment before running them on production.
Please read the article there is an answer to almost all your questions.
"| match" instead of "| grep". You can match using regex.
show running | match wan
matching parameters is case-sensitive.
regarding the "section" you can do something like this:

@matlear Your interest in DHCP relay is noted. Thanks for posting. We have an open feature request for that, but I do not have any ETA for when it will be implemented.
I really like these changes. We have the ability to scale our bandwidth without scaling our license. That's nice. Also the Home+Lab is invaluable to give our team the ability to experiment/learn TNSR before putting changes into production. This allows us to consider TNSR as a "go to" router in any implementation. Keep up the good work!
