The "same drawing copy pasted" thing drives me nuts too, once you see it you can't unsee it. I did the exact same frame by frame pause thing on a show last year and my roommate thought I was losing it. It doesn't fully ruin a story for me but it definitely yanks me out of the moment every single time.

Masking tape falls off after a few months in a hot attic or damp basement, and then you're standing there with a mystery wire and a Sharpie smudge. A $12 label maker with heat shrink tube takes maybe two extra seconds per wire and it actually survives the test of time. Plus half the time the tape wraps around itself and you can't even read your own handwriting anyway. Labeling is smart, but tape is the worst possible way to do it.
