QOTD: What's your favorite tool in your scrapping software?

[angiekey]

First, tell us what software you use to scrapbook ... then, tell us what your favorite tool is and why.

I use Photoshop CC to create my layouts, and my absolute favorite tool is the Content-Aware fill. If I have a photo that won't completely fill the frame or photo block on a layout, Content-Aware fill lets me quickly extend the sides or top/bottom of my photo with grass, sky, trees, or whatever is in the background of the pic, and 98.5% of the time, you can't tell it wasn't in the original shot.
