New Dynamic Designs at #blogger.com are great, but...

It needs a "New Post" button for the admin somehow. I helped myself with making a bookmark to start a new post.

Open the Blogger.com site, find your blog on the dashboard, hover over the "NEW POST" button, press right-mouse button and save it as a bookmark.
Then you can post from everywhere by selecting that bookmark. But this isn't the best solution.

And AdSense still needs to get integrated much better. Switched to sidebar view for now.
