Corkboard navigation

Say there are four cards in a row. When the fourth card is selected, then ‘right arrow’ should move the selection to the fifth card, on the row below. Right now nothing happens. Similar problem for ‘left arrow’ when the fifth card is selected. [Bug or feature?]

For now, it’s like “The aMAZEing Labyrinth”, if you know that game. The corkboard is the walls and you just can move back and forth on the tiles (index cards).

But since Scriv. knows about the order of the cards it should be possible to make the focus jump from last card in the 1st row to the first card in the 2nd row.

So, I think it’s not a bug, but room for enhancement.
