Hi Cordula.
If your theme has a custom stylesheet for admin, add the following line to the end.
ul.aws-oruw-wrap > li { float:left; }
Best!

No, i don´t have a special admin.css. And now?
Hi again.
Dashboard widget customization is not included or even coded, and can even be styled with CSS to fit practically all your needs (with a little debug and code knowledge).
