Alright, I know many of you still use Paint that comes together with your Windows. What's not to like? It's easy to use, able to capture and edit your screenshots, and even do a simple manipulation such as adding text and snipping the wanted picture.
What if you want something more? What if you want to be able to add different variants of text onto an area that is so hard to do on Paint? What if you want layers? You want layers to help you edit a specific part of your picture so that you don't perform a destructive edit?
There's a solution. There is GIMP. But GIMP is not made for normal Paint users. GIMP is made for advanced Photoshop user. Despite a Photoshop user myself, I find that I'm struggling when using GIMP. This is why Paint.net comes so useful for me. It provides the basics of Photoshop but never overwhelms you with advance tools that you probably never use. It's a bit more advanced than Paint itself and doesn't go overboard.
