From a visual point of view and in light of usability, the update makes Jetpack even worse than before.

Still we have useless background image that lets users feel like they are in a whole different app. Also, the intro page is totally useless, it's just propaganda, it has no use.

The "settings" page alone would be totally sufficient, but with module descriptions and fonfig buttons/ links *permanently* "on", I mean viewable/ clickable!

In the current state I consider this plugin user unfriendly - and my experience with clients showed just that, even in version 2.x.

Another thing, are the unresolved privacy issues and the many settings links/ redirections to a lot of different locations within WordPress admin dashboard.

WordPress plugin developers are being preached to use WordPress default admin styles, but the Automattic product Jetpack does not care for a lot of that. Bad role model.
