because it's a one-size-fits-all solution. If the thoughts in my head go from, "Can I see an example of this?" to "Okay can I give you some of my code and have you refactor it using this example?" to "now I want to actually edit the texture atlas" I don't have to switch programs or exert effort.

It's really convenient.

For a less contrived, more impressive example (multi-modality is insane!), see these: https://imgur.com/a/iy6FkBO

The above example shows me uploading 16 sprite tiles to GPT. The files were labeled 0-15 on my system. I uploaded them in two parts because there is a 10 file upload limit. I wanted to create a sprite sheet from these sprite tiles and didn't want to open an editor. So, I had it do it. After it worked, I realized I needed the three sprite sheets in varying colors (dirt, sand, and food) so I had it find/replace the dirt color with sand/food color. It then gave me download links to all three and all three were good results and saved me time.

(and yes, I know I don't have to compliment it. It's fun and makes work more enjoyable for me)
