Great, I'll download it right now! I was just thinking about the app yesterday, so I'll take this opportunity to share a few thoughts.
Currently, when I need to verify where specific colors are being used (in the image), the only way is to temporarily replace them with another color that stands out. This can become impractical with large palettes or in the long run. It would be fantastic to be able to set a "guide" color that acts as a highlighter without needing to make an actual change (in "Image Palette").
Equally convenient would be the ability to transfer collected colors to the "Map Palette" to reuse them in new images. Right now, the only way to do this is to gather everything externally and then re-import it.
Finally, the option to save different states would be a huge help. It would allow for more confident changes, comparing design alternatives, or even creating different options within the same work session, depending on how it's implemented.
Anyway, don't mind me, I'm just daydreaming; even without these features, the app is already magnificent.
Greetings, and thank you for your dedication! 😉
