The use case I am thinking of now seems to be more appropriate for apps like GitLab where sharing URLs from within the app might be useful, for example sending someone a link to a file like this:

https://d85snt1c8mqgrfxcd2o1.blah.company.com/gitlab/repo/bl...

Another issue with this is because of the navigation being done with frames, those URLs are somewhat hidden from the user. I have some thoughts on this, but they may be worth saving for the issue tracker as this appears to be an issue with the GitLab port and not Sandstorm itself.
