Hey! Thank you very much for this plugin, it is fantastic!

I'm just writing because I noticed that while using 'follow-hierarchy' the root directory is being properly discovered by 'find_project_root', but not used in FollowHierarchyLayout's method 'get_test_file'. This isn't the cleanest solution (gets rid of the relative path for the 'confirm') but it detects the test_file.
