First - thanks for the new beta, first impressions are pretty good from just a little messing about. Inking with a vector brush is now a good enough experience for me to start using it properly. Slow linework is still very wobbly but this can be fixed with stroke stabilising which has a good range of options to make it workable. Loving all that.
One thing I am having issues with on my Cintiq is trying to adjust the bezier nodes. If I can grab a handle or node (bit hit and miss) it just seems to shoot off all over the place. Will investigate more and see if it's a tablet vs mouse thing. I just want to hop and say .. nice job. It's looking great.
