I’m one of AP’s biggest fans and have been a tester since Alpha 1! Anyways, to hopefully help with answering one of your questions/inquiries, tool opacity. I say tool, because there’s brush opacity and even eraser opacity in other softwares, and also in AP! Opacity can be changed in each individual tool. Simply click one of them to set the minimum and maximum size and opacity. And if that doesn’t help you can also change the layer opacity at the bottom of each layer tab, on the left or right, depending on which side you have the xsheet set. I hope this helps fellow Alpha tester[Sam], and keep animating!
