WOW! What butt-ugly cable setups.
But, I can't say mine is any better.
Unless you want to make pretty, you just run the cables to the outlets as you hook them up and make do. Seems like that is what most of us do.
And really, how often do you need to trace or change a certain cable anyway? And if you bundle them all together, then you have to unbundle them to find that certain one.
And bundling has its own disadvantages. If one is damaged and has a short, being in a tight bundle will only make it more likely to cause a fire.
