Checklist feature in Deck cards

[yuisheaven]

Many huge kanban style boards added a feature to put a Checklist into your kanban Card (example Microsoft Azure Board and Trello).

I would really love to see this feature in Deck as well. Best would be with a preview on the card showing how many tasks of the connected checklist are already done

I see that it is possible to add this to the card already by putting - [ ] item in the description. All that needs to be done is to add a button next to the description saying "add checklist point" so that none-technical users can easily take use of the feature

I guess this is already solved with #4399
