The "scale to object" check boxes on stroke and also especially on the various effects (Gaussian Blur, outer shadow, inner shadow, etc) are both defaulted to always being off. For some people's workflow, I'm sure that's fine and maybe even preferable, but for the work I do, I almost always want it defaulted on and it really gets tedious checking the box on the effects panel for every different curve/shape that I draw. Frequently I forget and then when I expand or contract a complex project, some of the shadows and effects are all messed up.
Is there any way that you could give the user a choice to default it to always being on or off (user's choice) on your next update?
