It is already really tedious to delete items (especially since there isn't an Archive function). The modal confirmation box is super annoying. Supporting UNDO is a really important UX principle – and that's what a Recycle Bin does. If I accidentally delete something (very hard since it's behind a dropdown in the first place) I can retrieve the deleted item by going to the Recycle Bin. Adding the additional step is tedious.
Modal dialogs can help prevent errors in the first place but you don't need them if you have Undo.
Wrike is an expert-use system and should focus on being streamlined and efficient. Making things take 3 steps when they could take 2, and are potentially repeated often, makes it worse to use.
