I would very much like to see a Symmetry mode. Move layer, Re-size layer. Maybe even a shapes tool. I am loving this program. I understand its still in development, and it will take time to get all these features in. Keep up the good work Devs!
I really get a kick out of the Brush creation system! Node based function altering is pretty cool! I am looking forward to see what new Function nodes you will add in the future! I just wish I could save my custom brushes
