Hi, Kent!
I'm curious. I'm currently in 2.75a and I've noticed that collapse short edges is now a menu with three choices. I'm toying around with it but mostly, I've noticed that, if I reduce my distance to Five pixels, I'm getting a similar consistency to your setting of Thirty pixels! Is this due to the change in the dynotope line out or am I overlooking something? Also, I noticed you're able to make very quick adjustments to the size and strength of your brushes on the fly! Key strokes? I feel I have watched you explain this already but, for the life of me, I can't recall when or where! Sorry for the trouble!!
