I do not use this for two reasons:

- It is not open source.

- It does only run on Windows.

Alternatives include Krita, Pinta and The GIMP.

Yep, I'm happy with Pinta as Paint.NET alternative on macOS. Sometimes, I feel GIMP is a bit complicated when I typically want simple quick processes like cropping, paintbrush, etc.

this app is almost as old as dotNet and always felt like a showcase. it works, but understand your concerns. especially as the format is exclusive to their app (and the only way to have layers)
