Hello, I can see there are lots of great things about the app, but I can't find anything about how to eg use the oil bristle brush with Pencil pressure/opacity and to make it not resize as I paint. Ill health/not able to do lots of complicated settings, but will be able to use the app if I can just know how to do these settings for a brush. Thank you for any response. And if I can just ask also; will the 'how many buses/signs' stop? If not, the forum is unuseable.
