"Magic select" tool
Describe the solution you would like Like the magic select in paint.net, or wand select in other programs. Basically, wherever you click, a selection is made of all contiguous pixels of that color. This would also potentially allow transparency?
Describe alternatives you have considered Right now I have to export the project from PaintZ, import it into Pixlr, remove the transparency, and get it to where I need, which is sometimes back into PaintZ. I can't use a tool like remove.bg, as that leaves weird anti-aliasing, bad for pixel art.
Right now, the focus of PaintZ is primarily feature parity with classic MS Paint. For more advanced features like those found in Paint.net and Photoshop, Pixlr might be a better choice, and Photopea is great too.
