Wonderful work. We've built something similar inside our BusinessPress plugin (also manages updates, exposes hidden preferences & reduces WordPress branding). It would be great to join forces in fighting evil admin plugin notifications. Keep up the great work making WordPress the publisher-friendly CMS it deserves to be.

Great work, Thorsten

Every time I see Dobby instead of clutter, I briefly smile inside. 
House elves are great.

Thank you, Dobby!

Thank you very much for making this free for everyone :) 

Excellent work
