Cards: endless scroll desired
The display of channel stream and Articles seems to be based on endless scroll, but with Cards, when clicking on a category in the categories list (left sidebar), some or all of the Cards in that category may be hidden behind a "more" button, if the newest card in that category is older than newer Cards in different categories. Desirable behaviour: cards will be displayed regardless of their age, and will not be hidden by the "more" button.
