Hi patchouli,
Thank you for the comment.
First of all, the ability to upload a header banner (or logo) as you mentioned - should be in a module. This is why I separated it and make the apps + modules + textbots API so people can develop the extensions that allow to make any changes the user want.
As for the template, I still prefer to keep the user away from touching it. In the past, working with clients, only a few know how to change it by themselves without wrecking the entire design of the template.
The goal is not to make some sort of Google Pages or Frontpage - rather a fully working CMS that is easy to use, edit, and navigate and where the user can download 3rd party extensions (which I will make available soon)
Thanks again and I definitely accept all feedback to make this CMS better!
