File & pages picker: shift + click to select multiple adjacent items

It would be nice to be able to select multiple adjacent items in the file- and pages-picker like in macOS:

Select multiple items that are adjacent: Click the first item, then press the Shift key and click the last item. All items in between are included in the selection.

Multi select in general would be quite handy to bulk delete files inside files sections

In general, bulk editing of files and pages would be quite handy if you have lots of pages and files in your site and frequently reorder them. So not only for deletion, but also for moving multiple pages or files at once.
