It is indeed - I'm trying to manage a checklist in my main note, and my checklist contains items with nested items. Because each line is treated as a single object, I can't easily reorder that checklist. Dragging the parent list item doesn't bring its children along with it, making it really difficult to keep things organized.

Describe the solution you'd like
A clear and concise description of what you want to happen.

I'm hoping for a way to drag any group of items that have a tab-based parent/child relationship, without losing the ability to drag a single item. I

• If I try to drag a line with lines below that are tabbed, it should drag all those tabbed children
• If I try to drag a tabbed item, it shouldn't drag the parent or its siblings, only its own children

Dragging this parent line would also drag its children.

In this case, dragging the second child's line would also drag the grandchildren, but not its direct siblings or parent.

• Bonus points if dropping a tabbed element would adjust its tab depth based on the siblings of the place you move it to

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

I've tried highlighting the group and dragging that way, but the only item that moves is the one connected to the handle I interact with. I've also tried using the checklist/advanced checklist plugins, but they both seem to be unmaintained, and they lack basic functionality I need.

There are other list-based apps that accomplish this; see Workflowy for an example of the relationship behaviour I expect.
