I love the idea of the offline mode - it has me looking at GTDNext again. (I went to "Things" which I love, but I think my next phone is going to be an Android, and sadly they have no interest in supporting this.) But one thing I was trying out is "add to home screen" functionality out of Safari - to make it more like a desktop app. It seems like if you do this, then the offline functionality doesn't work?
When I'm online, synchronizing takes forever, if offline, it just gives a message saying "Safari cannot open the page. The error was: "FetchEvent.respondWith received and error: TypeError: The Internet connection appears to be offline."
Just curious if you tested this functionality, or if it is just designed not to be added to the home screen?
