This is awesome. Thanks for your efforts!
Seeing it's not signed by Apple, I was wondering if you'd be open for a donation to get you a proper account so the app can be distributed more "solidly" without Gatekeeper in the way.
Let me know. More than happy to get you in there.
Oh wow, this is a very generous offer. Thank you! It might take me a while to get the Apple Developer account to do so, not for the financial reasons. I've noted your concern and will get the app signed the moment I have a chance to do that.
