>>3400008me again. after searching even more, even on kickstarter, I stumpled upon this backback. It has a lot of pockets for my just throw in shit and my notebook fits. I like the idea of making it smaller/bigger depending on what you need.

Another idea would be to make an inner shelf out of eg. XPVC/Sintra/PVC Foam and put velcro on it to use regular deviders found in every camera backpack.
