Themes allow you to change the look and feel of your Drupal site. You can use themes contributed by others or create your own to share with the community. Contributed themes are not part of any official release and may not have optimized code/functionality for your purposes.
You can also create a sub-theme of an existing theme. A sub-theme inherits a parent theme's resources. Read more about Sub-theme structure and inheritance.
You can also view a full index of themes listing only their titles.

That comment is from a recent client meeting of mine. I put a lot of effort into making the content entry forms make sense. Actually, it's not that hard. It requires imaging what content entry will be like, and trying to make it better. Thinking through field naming conventions, labels and help text. Ordering the fields on the content entry forms with intention. And having a good theme — a theme that calms down the visual chaos of these forms.
