Trello lists and cards are area consuming, even though it is beneficial for drag and drop. Give some simple 'Note view' at left side as Onenote's section (lists) and pages (cards) to fit more items in the view - in app and web. When a card is selected, show its details just at the right side. This change may make Trello as a Note app too as already Trello can link cards as Zettelkasten note taking apps like Obsidian, Remnote, Roam Research etc.
