Http links in documentation pages does not have a "back" button

Hi Supportteam,

we have http links to different web-sites in the documentaion page. When you click on those links, RDM will open the link with in the doco page windows. That is okay.
But you are not able to go back to the main docu page. There is on "back" button.
The only way we found is ALT + [arrow left]

Here is a test page:

# Test Page

Follow this link and try to go back to this page.

Would it be possible to implement a button to go "back" to the last page ? Like in a Web-Browser.

thx Michael
