I understand this would be really hard to make, but there would just be so many uses, it'd be the equivalent of introducing 10 new elements or something X'D Basically what I'm suggesting is something like the scale features in image editors like MSPaint and GIMP, where you can select part of the screen and scale it up or down, except instead of changing 1 pixel of green to 4 pixels of green, it would change 1 particle of DUST to 4 particles of DUST.

Again I know this would be extremely difficult to do, but imagine the time it would save with artworks where someone accidentally makes part of it too big, with electronics where someone wants to shrink or scale up a part to make it fit, with making collages of other saves by squishing them into thumbnails. I understand the challenges here but there's a monumental number of uses a scale tool would open up, or at the very least a new element that causes all nearby elements to expand. It would be really really cool!
