It would be useful if dragging the corner would show the new size (dynamically) rather than having to gauge it visually.
Yes, you can do that in the Full Page Editor, just double click just outside the preview (or right click & choose edit page).
There you can drag to resize and see the size, re-position and move images to a different page. Re-positioning will automatically change the sorting to Freehand. There's a little red F top right, as is on the preview too.
There's lots more in the Full Page Editor, right click on an image to see the list!
