Allow users to bulk review, approve, or dismiss transactions from the web/desktop version of Piere, similar to the swipe-to-review (Transaction Stacks) experience on mobile. This would make it much faster to process large numbers of transactions on desktop, where a mouse and keyboard interface lends itself well to batch actions. Use cases include reviewing many transactions at once, bulk categorizing, or bulk dismissing flagged items without needing to switch to the mobile app.
