Hello
Deleting an element in the hierarchy may be tricky since it may occur without intention - like by pressing DEL key in place of any other. Undo tool is of course very helpful, but the deletion may occur (even worse) without notice. Can I set a confirmation window to appear before deletion?
This option is not yet available for elements; only plugins and collections. We might add that to our roadmap later. In the meantime, you can use Control + F and the Undo arrow. You can make a feature request here: https://feedback.weweb.io/make-a-request/
