It's clear the new interface will be "TURNED ON" at some point in the not to distant future, what functionality will you lose? Please report some issues!
I use the new interface, "report issues", and before logging off always switch back to, and use, the old interface. I'm hoping this serves as a vote for the old interface until the new interface brings forward all the functionality of the old interface.
Missing features:
Reporting URL channels, by channel and day, (BOTH feature) If you want to analyze performance on a daily basis, this feature is critical.
Templates. Existing templates are gone?
Almost useless features:
Data by Bid Type (CPM or PPC). Without accurate CPM impression data this information has limited utility other than confirming how poorly CPM pays for certain types of sites.
Pagination of results. Now you must scroll and use the pagination buttons. How about a default ALL setting. I'd far rather just scroll through all the data. I have generated some reports that took the browser "minutes" to render! I can live with that as long as I can still get the data.
Desired features:
Close the graph? Many times I just want to see the data.
Other:
Excessive clicks for the same information in the old interface. Granted new functionality may require additional navigation.
I've used "report issue" for all of the above, minor, or major. I really don't want to lose functionality.
(For example I just learned IE7/IE8 dumped the "save offline" feature when I needed it the other day. A disappointment!).
