When a pinboard item is pasted from the pinboard, please make it move automatically to the beginning of the pinboard, on the left side.
Pinboard items are used with different frequencies. With this behavior, items used more often would gradually move toward the left, while less-used items would move toward the right.
This would make frequently used items easier to find. It would also make it easier to occasionally check the less-used items on the right side and delete the ones that are no longer needed.
