47 | * Larger values basically give you larger brushes and larger bristle spacing. For example, a value of 4 will multiply your base brush size by 4, but the bristles will be 4 times more spaced apart. | 48 | * Larger values basically give you larger brushes and larger bristle spacing.

Large values will increase the brush size a bit because of the bristles spreading around, but not by much. | 56 | * At other values, the bristles are offset randomly.

59 | This controls the density of bristles. Scale takes a number of bristles and expands or compresses them into a denser area, whereas density takes a fixed area and determines the number of bristles in it.

101 | Be aware that this feature is a bit buggy though. It's Supposed to take the color from the current layer, but some buggy behavior causes it to often use the last layer you've painted on (with a non-Bristle brush?) as source. To avoid these weird behaviors, stick to just one layer, or paint something on the current active layer first with another brush (such as a Pixel brush). | 104 | Be aware that this feature is a bit buggy though.
