I use trello cards to manage my discussions with different stakeholders. so there is one card for each person and then i keep adding checklists about the points to be discussed.
Now when i discuss those points, i tick it off and keep adding new items in that checklist for next discussions.
What would be great, when I tick the item off, it should disappear from the card and untick ones should shift up.
Maybe in setting of the card, you can have extra feature in front of checklist: disaapearing if completed: ON
Thank you.
