Layout features/settings changed after update

Looking for help with some simple Layout settings that I don’t see in the update.

First is when scaling an imported image (photo). I’d like the images imported to all be the same dimensions. I used to be able to snap the position of one corner of each image, then automatically reference the new image to match the size of previous image. I don’t see the settings to do this. I also used to be able to scale an image to exactly 50% the size of when it was imported, with the text showing the scale percentage near the cursor. Help?
