I just found a new option in my Google account. The ability to activate Google Gears for AdWords. This stores all you account data on your local computer for faster load times. Look for an offline icon on the top right of your AdWords account.

When you click on it you are prompted with the option to continue and activate:

This was reported by Search Engine Land last week:

Instead of loading the data off Google’s servers each time you click on a section in the AdWords console, Google will load the data off your local computer. Google said, “each time you access AdWords, your data loads directly from your computer, making your experience much faster.”

Do you have the offline option in your account?
