I had an idea earlier that I would like to kick around. I was reorganizing my bags and it struck me that if one of my large clear pouches had sewn dividers separating the interior into 3 equal pockets, I could store stuff more easily in a vertical fashion inside my Large Cafe Bag. Then while I was mulling on this, and potential designs it occurred to me that if I had an insert with some firmness (akin to the backboard of the Freudian Slip), and if I had a 2x3 arrangment of pockets I could do even more and I could orient the pockets to face up, instead of sideways.
Then it further occurred to me that I would fing it of even greater utility, if the pockets were sized to carry a variety of current Tom Bin pouches. Indeed, the pockets could be designed to fit from a mini padded pouch with contents to a small padded pouch with contents and the bck could be set to hold a medium padded pouch. Perhaps the back could be similar to the Freudian Slip design, but hold folded-in-half paper sideways, and a medium pouch pocket built on top of that. O-Rings could be set next to each pocket as well, to act as a tether for the pouch and a key strap.
Right now I am using a large clear pouch in Dyneema Solar, with the contents unfortunately sliding all to the bottom. I am thinking of taking a plastic folder and breaking it in half to use as a full-sized back board, and gluing pockets to it. This would allow me to better utilize the vertical nature of the bag.
