Adjustments for Learner View

Currently the learner view of the prime surface is fairly static and I have no idea how to modify it. I would like to make adjustments to the following:

1. Prime playbar should have a "Back" button (Makes no sense to add an extra button within the scenes).

2. I would like to cancel the "Did you know" area. This text is irrelevant for our users/learners and provides special info for admin, authors etc.

3. If the "Did you know" area must remain, I can live with it, provided I can create text myself and delete standard text.

4. The "Help" button gets the learner to a help list addressing all issues for learner AND admin, author etc - Not so good. Would only like to address the help for the learner.

5. The little labels on "Course Effectiveness" are not needed, nor wanted. Statistics are only viewed by admin and management. I would like to take this feature out.

6. E-mail notifications are currently a nuisance. I checked all notifications as "No send", except the first enrolment. However there are still constant mails, like this: "You have complete course xyz" or the remarks, which have been added are coming once again per e-mail. the learners are flooded with e-mails, as well as the admin, author etc., even though the e-mails have been unchecked?

In general it would be better to have no Prime enforced learner actions and notifications, but rather that the admin and authors have the option to add what they need within their particular situation.

Is there a way to do this ?

Thank you
