Thank you. Right now we have checklists ;) Full-featured "subtasks" is a very interesting matter and we are working an a default support for that. Currently, you might "implement" this by adding a references called "subtasks". You also could create an aggregation to sum up costs/time estimates of these subtasks.

Yes would also love subtasks, start with a skeleton then add the detailed meat of the work like how the interface works with https://workflowy.com
