visibility of card titles on the board is not optimal for grouping when we have a lot of cards

[philipverlinden]

Retros with a lot of cards, it's difficult to group. When we zoom out the card content becomes unreadable.

• can we expand/collapse both sides?
• can the zoom out be improved so we see more cards on the screen but the title remains readable
  or
• can it become a list where we can drag and drop items under others (like a treeview)
