If I want to erase the white around an object

Funny, this is literally one of the primary examples of something that GIMP did better than Photoshop (at least back when I was actively using GIMP a lot). GIMP has the “color-to-alpha” tool that allows for backgrounds to be faded into transparency (including converting the border of that object into translucent pixels that don’t have the hint of the old background), which I remember being the easiest way to remove sky or other background from an object, and to place that object into a new background or other image.

I’m guessing that in the 10 years since, Photoshop has a bunch of those AI tools that can do that specific function almost automatically. But GIMP does do that specific task pretty well.
