It’s pretty easy to edit the exported course. You just need to untar/unzip it,
edit the policy.json file, and then tar/gzip it again.
In the policy.json you just need to change the order of the tabs so that
courseware is first.
If you need more details, let me know (you can also try to find me on Slack).
Can I confirm that you encountered this problem when you exported a course from
edx.org and then imported it into a dogwood devstack?
Thanks,
Peter
