Title: fix #12 with withVisible()

BTW, here is something I have never figured out in GitHub: if I forked your repository, and later you updated it; then how do I sync with you so that my new pull request only contains the commits that I made? For example, in this case, only the last commit is meant to go to you, but all 8 commits are shown here.
