Great Frontend poor Backend

This plugin produces great emails, however the backend is poor!

1. My Website in the footer look at the widget when it is in a wide sidebar
2. All verified group is set as private but shows on the widget
3. I can not select assign and move members in bulk to a group only one at a time (500+ members)
4. When I select send email it sends only 1 and says ok!
5. On previous sendings (Actions = no options) can not delete failed sendings.

With number 4 I had another email plugin which sent to all members so it is not a server thing.

The plugin was purchased after being reccomended!
