Deep Links for LabCoat is a utility app that does one thing and only one
thing: it allows you to open links to non-gitlab.com GitLab instances -
for example, gitlab.gnome.org - in the LabCoat for GitLab app.

Known issues:

LabCoat opens but link does not load - Make sure you are signed in to an
account on the Gitlab instance you are trying to access. LabCoat is
unable to display anything from a Gitlab instance without a valid
personal access token - even if the url you are trying to access is public
on the web.
