Introduce default collapse level for lists
So if a user visits the list the first time, they see the list fully collapsed. The same applies to guest users who visit a published list
Not the complete solution, but after the latest checkvist update public lists are shown to not logged users expanded to 1 level only, deeper tasks are collapsed.
It woud be really helpful for public lists to open in the fully collapsed state. That's because a first-time visitor to a list needs to take in the big picture first and doesn't want to be overwhelmed by all the details.
