Better todo list with indexes

[TomaszSzyborski]

I tried to use the todo/trello cards from examples.
But the drag and drop feature effectively appends new cards as children in column.
Id like to have insert at specific index, like insert a card between cards.
I've found an example how to do it in quasar and vue here https://codesandbox.io/s/94yv5v6vrw?file=/index.js:405-447
is this behaviour repoducible in NiceGUI?

In principle, this should be possible.
This discussion about inserting elements at a specific index might be relevant: #489.
