I don't really know, It's probably one of those things where you think "wouldn't it be cool if" but when applied to real life is impractical. I have a picture in my head of something that holds each individual key, is heavy duty and makes finding a specific key quick and easy. Like I said it is one of those things... When I say efficiency I mean being able to find something without rummaging through everything. Yes I know it is picky and probably impractical but that is who I am. Not that finding a key cap in a tackle box would take longer than a few minutes it's more like the idea that put's me off. Anyways, Like I said either I deal or invent something.
