On a foldable phone Cards 2.0 is usually way too wide and a whole card may not even fit in on one screen due to the wonky ratio. But I really like the look of the cards compared to Columns. Like the previews on columns aren't ideal. Could we just get Cards 2.0 but with multiple configurable columns?
