For fast testing, it would be really useful to push verbose output directly to the console. I appreciate that it would be up to the user to set appropriate filter(s) to make it useful (eg., masking tablist every two seconds). Something like
perms verbose log
same as "on" or "record" except to console/log. Just a thought...

Just execute the verbose command from the console.

My mistake. I interpreted "send you an alert in chat" as in-game. Obviously, chat is reported to the console, so...
perms verbose on
does report to the console/log, while
perms verbose record
does not.

This is an extremely useful feature. Thank you.

yes.
the record option of the verbose command, followed by the paste option results in posting the checked perms on git.github.com
