I believe the crucial lacking feature is custom brushes, but not only small customization like it is now. But more advance. Different types, like it is in affinity designer. They have options like “Pencils, Pens, Vector Shader Brushes, Watercolours, Acrylics, Artista Brushes etc” There is a lot of possibilities with this. Vectornator already proved is better in lots of way. I believe one of the most important new feature is the advanced custom brushes. This app is about lines… More types of lines… guys… Make it happen!
