i'm working on the update, getting a good progress on both the pixel designer and the pixel editor, will release it once everything is strongly connected and organized, the new workflow will be similar to the previous version for sprite creation with materials and randomization, but with the ability of creating your own sprites by importing sprite sheets for each layer or but drawing them inside the app, creating a pixel editor only is easy since it's just basic but with such a designer it should be unique and follow the sprite workflow, ie. colors indexed in materials and layers with cells ability that can be switched, am so sorry for being so late but 3 years of learning and making the same project again and again without giving up and also focusing on my real life has made me reach a solid ground for the app in Godot 4, also it's planned to be released as a plugin for Godot4 so u can create and edit the sprites inside the engine, thank you ^^
