Congratulations, looks like a cool app, I'm hoping I'll eventually catch up with being feature rich like yours. I've only just started, being hacking on it for a month now but am looking to do something pretty similar. I think we've had a few ideas the same - and amrescratching the same itch. Your 4 years ahead though :-) :-) https://edit-this.page/help is my humble work in progress.

Best of luck to you all!
