Hi, I dont see a "Open" link in the details panel.  I can see hyperlinks for the commit and my name but I cant click on them or anything.

I spend most of my time in the main view, so my suggestion was to right-click the branch in the Branches window and select context menu "Copy GitHub URL"

(btw I'm on Ubuntu 18.04, running SmartGit 18.2 p9)
