New task lists in project boards and issue search

[leighmcculloch]

I'm loving the new task lists features that showed up today. It would be really helpful if there were two additional places that task lists surfaced:

• Project Boards – It'd be super helpful if there was a way to have a project board filtered to show all the sub-tasks of a task. It would help quickly zoom in / focus on the tasks related to some larger piece of work.
• Issue Search – It'd also be helpful, although less critical I think, if there was a way to search for issues that are tracked by another issue.

Thanks!

• Searching for Issues that are not tracked by another issue. Useful when grooming the backlog.

In the issue search, we could have tasks:n analogous to comments:n, and is:tracked. How about tasks:>90% for all PRs that are almost ready to merge!

Is is:tracked really a thing? I could find no documentation on it, and not sure if it does anything in issue search
