I ended up using Photoshop, as that has antialiasing. I still had to do a lot manually, but it worked like I wanted it to work. Hope that antialiasing would get added at some point.

I am trying to do that. And it indeed is possible, as shown below (done with the Lasso selection tool). When deleting the selection, it works like I want it to work, where it makes pixels partially transparent. This for some reason does not work with the selection wand. This does not work either, as seen in the background here: Even if I have the object selected and I use the Feather Object, it does not work.

Both of these suggestions still do not work sadly.

It did not work as I wanted it to. Even after using that tool, it still didn't smooth the make the pixels near the selection edge partially transparent.

Thank you, I will try it!

How do I make it, so that if I use the wand tool, it "part selects" edge pixels (like in the image attached)? I already set Selection Quality to "Smooth selection edges" but it still is exclusively pixelated (See second image attached). How do I make the selection smooth, so that when I press the Delete key, it isn't a binary "Delete" and "Don't delete", but rather a "Delete", "Delete partially", "Don't delete"? (36% Tolerance)
