Would be nice to have bigger tool sizes for the brush paint tools. For example, I would like to create a green object at a very
high layer resolution and use a red brush paint tool to create a gradient that covers the whole object and paints it from green to red. So the tool size needs to be about 200% of the highest layer ( box ) size to get a nice, even and smooth gradient from one color to the other color.

A
dedicated Gradient Paint Tool would also be a nice solution.
