Jolly Time Popcorn Kernels

Now, if only I would get a way to make Photo remember to use a 5x5 or 17x17 color picker sample (needed in large resolutions to not pick an odd-unexpected color of 1px with most brushes, specially textured ones) -as I use ALT (programmed in my pen button) to temp-pick colors as I paint, at top speed- then it all would be perfect. I wonder if it is possible to add to the assistant, in case just making it work by default is too much of a revamp of the code.
