So in clip/manga studio there's a whole set of tools for panels that create these vector boxes you can move around and split. They are also folders that mask everything outside the lines, so I put all the layers for each panel in them. The end result is that I end up with a ton of layers for each panel and my computer slows down. The sensible thing would be to just have one layer for line art, another for color, and so on; then make (as you say) thin white boxes for the gutters on top.
But I haven't yet, probably because I think "well what about all these fancy features in my software? Won't they get, like, lonely or something?" Its the dumbest reason, I know. I'll probably streamline my whole workflow regardless but.... ugh.
You make me sad, Smith Micro. You make me sad.
