I was looking for a way to generate a grind in Paint.NET and I came here to test your plugin.
I need a 1024x1024 grid and 2048x2048... Your slider is limited to 1000 only. Please fix.
Also don't you think it'd be far more flexible if you'd allow both X and Y size? I'm sure there's a person somewhere who wants a 2:1 grid or something like that.
