Sorry for the long delay. It’s a long story. But it’s in public beta in Hook version 1.4 (3143) . To be clear, 1.4 is not beta software. It’s just the sync tab/function that is presented as beta.
Our co-founder, Brian, came up with the design and implemented it. (It had been ready for testing for a quite a while but it took us a long time to be able to get to it.) I’m delighted with his work. From the user’s perspective the sync functionality in Hook looks very simple. I find it quite elegant. I hope you will enjoy it too.
