Within vPlan it is possible to select and drag multiple cards.
So you can drag multiple cards to another day or back in the backlog at the same time.
You can select the cards separately by pressing and holding Control (Windows) or Command (Apple). Click on all the cards you want to select and easily drag them to another day.
By pressing Shift you can also easily select a whole series of cards. Click on the top and bottom card of the selection you want to select. All cards in between will also be selected automatically.
When you want to select the selected cards, you can pick up a card and move it by drag & drop. The other selected cards will move automatically. This takes into account the difference in days of the selected cards. You will also immediately see the number of cards that you have selected, which in this case are 5.
