I can see myself having to get to grips with the template system fairly quickly. Out of the box Bartik is not doing what I want it to do. Will have to sort that out. As I understand it though, subthemes are still well supported so extending this shouldn't be that much of an issue.
So, to start with;
- Tweak the header to allow the logo to be hard up against the left of the viewport
- Change the heading colour. Despite the theme being managed by the color module the headings are not. They appear to only have one colour and that makes Bartik only suitable for lighter themes.
