Task management applications like TickTick and Todoist provide a simple way to enter and display tasks and subtasks as a nested hierarchy. This feature would make Anytype much more useful for task management.
HOW COULD IT BE DONE
Add a Task object to a Page. Enter subtasks in parent task page. Show subtasks on the Page under the parent task block as a nested hierarchy like the “Toggle” Text Style.
REAL WORLD USE CASES
The task hierarchy display would be useful for task management.
Awkward workaround: Enter subtasks in parent task page. Enable Toggle Text Style on parent task block. Copy subtasks under parent task block.
Seems like this could be easily implemented since there already is a mechanism to show certain relations in links.
As for sets, I’m not really sure if anything would even need to be changed since the OP is recommending to use an relation which can already be shown in sets. Unless I’m not understanding their request correctly.
Of course, if you wanted a more specific integration, you could try and implement some specific code to make it function more like Todoist and TickTick. But that can kinda be implemented with the group function after it is released. If you grouped objects by their parent relation, you would get something like what TickTick and Todoist do.
