We've been telling people for years to use the breadcrumb trail to navigate around the site - "don't press back, use the breadcrumb trail".
- Go to any course on the site
- Go to files area
- Upload your file or whatever you wanted to do
- Click on the course short-name in the breadcrumb trail to get back to the course page
– Ooops – You're lost somewhere in the file repository.
Could I suggest that this is a massive usability regression??
