Thanks for a great product but it clearly has some issues at times - often such as adding brush shapes into the tool and then applying the brush (just one example). It just suddenly stops and disappears on my mac (10.14). Can't see any real pattern to the crashes but modifying the default brushes and then applying them causes a crash (such as using sequences or dots or brush shapes or images for the colour etc). It is still a very useful application but one that I have to save work quite regularly (such as saving a brush stroke)
One account,
many possibilities
