I wish there was an option between Thumbs Up and Thumbs Down. The features are great and we do use the plugin daily. However, I need to echo the previous thumbs-down vote: New bugs are introduced with every new release. This causes us serious productivity loss in some instances. This project has the potential to be incredible, but it needs much more serious QA and attention to detail.
The features are in theory great, but the application has many bug regressions and broken features in every new version. Even bugs which seemed fixed, break every third update. Basically, it's becoming a chore to use because of the UI issues (e.g. the sort and filtering on the images tab).
