Word processors, still imitating typewriters

Right after we finish ridding the world of “floppy-disk-to-save” icons, I propose we remove this bit of obtuse skeumorphism from the default view in word processors like Google Docs:

the margin setting thingy on a typewriter
Who uses this anymore?

I vaguely remember using one of these to adjust margins and such on a real typewriter once. Its possible I used one to eek out an extra page in a school report during junior high. Since then? Wasted screen space!

Act like a modern device, word processors. Hide that stuff in a menu somewhere!
