I was very critical of adcenter when they released a buggy product too early out of beta, but they have been slowly improving it and with the recent update it is now quite useable and useful - much less buggy, now its possible to do up-to-date editing of campaigns with conversion data and everything! Good job.

Things I notice still need fixing:

Add a select/delete keyword option to the main display

No custom data range selection - why?

Global negative keywords are still a mess

Conversion data not very accurate (don't know if this is an adcenter problem though)

Keep the structure of the last repost as default - its damn annoying to have to manually add conversion data to every report. And the report graphs do not update as you move through new pages of data.
