Poorly Documented Feature: Canned Responses in Delegated Accounts (Gmail)

It's no secret. We love Gmail. However, sometimes, there are features that don't get used much that are absolute "killer" features - but it turns out they're not always well documented.

A common scenario is creating generic "role based" accounts that receive large volumes of mail, and to then delegate access to this mailbox to several individuals to deal with the responses.

Of course, a lot of incoming emails means a lot of outgoing responses (often the exact same thing hundreds of times), and there's a really handy feature, Canned Responses, in Labs that makes this a pleasure.

Labs Canned Responses.
Thank you Googler Chad P,
bulk email responders LOVE you.

However, if you switch across to a delegated account, shock, horror!
No Labs!
Does that mean no canned responses in delegated accounts? No it does not (phew)...
