Sure Daniel, I also discussed a lot in Annecy with Ondrej, about both Lazybrush, TVPaint, the 2D animation software industry, etc ...Regarding the Aggressive mode we already tried something similar but we were not able to safely recognise the user just finished drawing of the scribble (using TVP plug-in SDK). We'll discuss this option with TVPaint team and see whether there is some more elegant solution.
I hope Ondrej will report you all this.
We will have many things to talk together in the coming days.
We will exchange some emails, maybe not at the beginning of the week (there is a lot to do just after Annecy), but probably just after.
