[Feature request] (Optionally) load completed tasks automatically

Currently, you have to explicitly click a button in order to load completed tasks every time you open a task list. However, in some cases, I always want to have completed tasks shown without having to click a button.

For example, I have a list I use as a grocery list, to which I do not frequently add new items, but I frequently check and uncheck the same items.

I would appreciate it a lot if there was a configurable option (ideally per list) whether or not to load completed tasks by default.

Also, I think completed subtasks whose parent task is not completed yet should always be shown. In my opinion, it is confusing that it only shows the non-completed subtasks (hence giving you an incomplete picture). In other words, it would make more sense to show all subtasks (including completed ones) of non-completed tasks.

Moreover, when you click the "load all completed tasks" button, it gets replaced by a "delete all completed tasks" button in the exact same location. I think this is a bit risky since you could unintentionally click it out of habit when you don't realize completed tasks are already loaded.

No file, test, or entry point is named. Start by locating the task-list loading controls and list settings, then verify that completed tasks can be configured per list, completed subtasks remain visible under incomplete parents, and loading tasks does not expose a destructive action in the same position.
