Local Business Ads:
Allow the coupons one can create through the Local Business Center to be attached to an ad or created through the AdWords interface and connected to an ad.
MCC:
If an MCC creates an account, allow the MCC to have full control of the account settings without having to log into the account directly.
Reporting:
Add 'external ID' and 'email address' as options for reporting options.
API:
(I know the API team has heard this plenty of times, but until it's implemented...) Preface rows with the external ID or email address when requesting MCC reports.
I'll be passing your ideas shortly, in this week's Advertiser Feedback Report.
And, I hope there'll be a bunch more by this time next week. ;)
