I think it would be great to get some features-ideas from the todoist. such as: In the categories, as many subcategories as you want. You make sections. It is displayed as a list or as a board. You make as many sub-tasks as you want and in each one you can put a description (note), as well as set a date - reminder - comment. You can move a task or sub-task under any task, or sub-task, or section, or category you want! It also works very well with labels. It is also very important that it works in Wear OS.
