I removed my Chrome Extension from the store in February. It was averaging about £30 per a month in sales and the cost of keeping up-to-date with the changes in Chrome/the extension store seemed hardly worth it.

The thing which really pushed me over the edge was their new developer dashboard, it was a step in the right direction but what missing some key features which were present in the old dashboard. Googles solution? Make us use both dashboards for almost a year.
