I like the app idea and will be happy to use it over Things 3, but there are some features that are inconvenient and all GoodTask 3 powers doesn't let me to use it.
Notes
This is something terrible. If I need to make a note (which I add to every task in my list) it's a pain, because I need to scroll to it on iOS and Mac. A notes section should be right after a task name. The same is on Mac and the notes section is at the very bottom.
Also, it opens in a "new window" which is also inconvenient. This is best implemented in Things 3 for ex.
Subtasks
This is also much better in Things 3. It's on the same screen so I don't have to scroll pages to choose what I need.
Widget
On Mac a widget can show full task name, but on iOS it shows only the first line. Want to see a whole task name on iOS widget.
Today widget shows tasks and than calendar events. It's wrong. Should be: Calendar events and than tasks.
URLs
I can add only one url to a task. But very often there are 2 or more needed to be added.
Badges on icon
The app works in a background and sync very fast any changes which I can see on widget, but badge on the icon doesn't change till I open the app. It's also irritating.
This is user experience and I'm not irritated, this are just the things I'd like to see in such app with great potential. I really like to use the app, but without these things it's not possible to me. Dear developer, please, add this features and I can guaranty that lot's of people will move to GoodTask 3 from other ToDo managers.
