Right now in List view, we can choose to show subtasks separately, all collapsed, or all expanded.

I would love a fourth option to respect manually collapsed and expanded subtasks - i.e., if you have all subtasks collapsed as default, but then manually expand some of them, I would love it if it could be remembered that those particular ones were expanded.

This would be useful for when you want to keep a List neat by using "collapse all", but have some particular tasks you want to see the subtasks of on each load.

I would not necessarily want this all the time - sometimes defaulting to collapsed is better - so I do think a new "manual" option that augments the others would be useful.

Maybe it would be a toggle, like "Collapse all" with a toggle for "manual override".
