Been there. I ran a spreadsheet for almost a year and it got to the point where I had 60 something rows and could not tell you what half of them were without clicking into each one. What finally fixed it for me was keeping the paper index but adding one small thing: I write the date next to each entry, so when I look at the page I can see what I have not touched in a while. That alone stopped me from duplicating stuff I had already logged months back. The other trick is to leave a few blank lines between sections so you can squeeze in new names without rewriting the whole page. Ten seconds to add something is about right, and honestly the flipping is the whole point. You see everything at once, which no menu screen ever really gives you.

The weird part about those click-together days is you can't trust em. Had a run like that on a 172 panel upgrade, everything landed perfect, and I walked around feeling like hot stuff for a week. Then the next job humbled me so bad I started double-checking pins I'd already checked twice. What gets me is how much of it comes down to how the last guy left the plane, clean routing and good splices and you look like a hero, hack job and you pay for his sins.
