Google has been testing out two new features for AdWords advertisers, including longer text ads and a desktop application to manage AdWords campaigns.

AdWords Editor, which launched in beta on Tuesday, is a downloadable account management application for Windows that lets users make changes to multiple AdWords campaigns, in multiple accounts, and then upload changes in bulk to Google's system.

According to the FAQ on Google's site, "AdWords Editor can work for any Google AdWords advertiser with any size account. The application is particularly useful for advertisers with large accounts containing multiple campaigns and long keyword lists."
