I have been thinking I need to arrange my bag better and this is a very good idea and list. Along with all this information from here I got an add in my email just yesterday for the following pack:
https://www.rescue-essentials.com/5-11-operator-als-backpack-26l-black/

I am thinking something like this may be adaptable to the whole "segment" idea and also make your stuff easy to sort/find when you need it. As it runs a bit over two hundred bucks for the bag, this is not going to be an impulse purchase - however, it does get me to thinking.

With some zip bags, colored tags/tape and maybe some specific types of pouches I can build my own "operator" back pack. While the advertised version I am sure is "low drag & high speed" I will settle for a home-brew version that has a less tactical look and still has the same functional concept. I'll have to spend some time with everything laid out and do some thinking...

Thanks!
