Good idea, but maybe a feature where you select the schematic, then go to the menu for positioning, scale and stuff, find the *new* button that says "Schematic Manipulation" or something like that, and it opens a menu something like the Import Schematic menu, except when you select blocks it shows settings for that block like glow, alpha, color, a bunch of things like that. You should also be able to select blocks that you want to remove, or select an area that you want to fill with blocks. Though, this might be pretty hard to do, I don't know anything about how MI is made.
