Thank you! It looks okay, but I'm just considering whether it's worth adding and whether it clutters up the About page unnecessarily..

As author of this pull request, my opinion would be a bit subjective. I frequently make use of the back button in title bar of other apps and find this feature to be a convenient way to navigate.

Feel free to merge or reject the pull request as you wish.

Thank you for your patience. I've procrastinated making a final decision, but I'm still thinking about it. Thank you again for your various contributions to the app!
