More Gradient tools and settings for Weight Painting

So far there are only two tools for gradients under weight painting and that is linear and radial. We deserve more shapes and patterns apply weights. There are also no settings whatsoever to control the existing ones either. I want to be able to set the linear gradient to both left and right at the same time and not just one direction. The radial gradient should also have an option for sphere or cylinder. Another possibility would be able to allow the user to manually design their own gradient tools in the program
