[mrtrizer]

            // This check doesn't cover cases where Assets dir is a git repo, or a project is within a bigger repo
            // I also got feedback that this code is hard to read, probably need to add a comment or refactor it
            return Path.GetFullPath(result.Output.Trim()) != Directory.GetCurrentDirectory() || Path.GetFullPath(PhysicalPath) == Path.GetFullPath(Application.dataPath);
