How do I script it? OF's automation is a must-have, as that's how I integrate it with my other apps. Extensive Shortcuts support (ala Things) is a minimum. AppleScript or JavaScript is better.
I won't use a to-do app without a start date. Don't remind me to renew my driver's license 3 years in advance. I don't even want to see that. Everything that's due far in the future that I couldn't be working on today even if I wanted to is just a distraction.
I can't deep link directly to an item. That means I can't use it with things like Hookmark, or have a note in another app that links back to its related project.
I can't legally use it without end-to-end encryption. That's a deal breaker for anyone in a regulated industry, and I don't want to have one to-do app for work and another for personal stuff.
This looks really cool! Each one of the above items would keep it out of the running for me, though.
