The layout of Application Builder has been improved to put more focus on the preview and make managing views and cards easier. Views and cards are now structured like a file tree, with cards being nested and positionally arranged under views.
To add a new card, click on the insert menu and then select the desired card.
Alternatively, insert a new card in-position by hovering between a view or row and clicking the insert button.
To rearrange cards, simply click and drag to reposition or move a card to a different view.
You can also hover over a card or view to reveal a menu for accessing various card operations and their associated keyboard shortcuts.
