Do you really need that Python script? I think you could end up with a nicer user experience if you rewrote those 264 lines to JS with Electron.

Great effort and reason to create this! I'm accustomed to using the Magic Wand tool in Paint.net[1] and Pinta[2] to select pixels based on color. Any chance you could add that functionality?

The name of this project brought many memories of the HP 48G to the forefront of my mind, after so many years. Its 1 bpp pixelated icons and drawings were indeed called GROBs - there are collections of these online. What a coincidental but fine name for a pixel-capable graphics editor.

Looks minimalistic and nice to use. I might try making a pixel icon for my app with it.
