Those are two totally different things. Windows take a screenshot of everything visible. Cmd+shift+4 on a Mac allows to select a region to save as a screenshot. Finally, if you are on Mac, this update provides node level acreenshot, allowing you to save an image of a HTML node with just one click, no need to drag the cursor. This is especially useful if the node takes more space than the viewport since before you had to stitch screenshots together.
Agreeing on 100% of that. Just wanted to point out taking screenshots in windows isn't "harder". (You can also alt-prtscr for just the active window, or use the snipping tool to screenshot a region).
