So far I have been very happy with my vertical organizer. I have my camera now siting up high in my bag, in a padded pouch, so it doesn't eat up an inside front pocket. I still have my keystrap attached but I think that I will be removing it as I seem to just be leaving the pouch in place and using it as a padded zippered pocket.
Now that I have a working prototype, I am thinking of improvements to my design. I use the loop (soft side) Velcro (I am calling it Velcro but it was a different brand of that stuff) on the pouches so if I use the pouches without the organizer, they will work fine and not be hooking stuff. So, I was thinking what if I had a full size sheet of the hook side? And what if I had squares to cover those sections I didn't need exposed in a particular configuration? And what if I had a built in pocket to store the square covers that were not being used? This prevent the hooks from grabbing at stuff it shouldn't, and allow me versatility in form to addressing my needs for that day.
So I will at some future point be making a 2.0 version, with a greater attention to details. I even thought about cannibalizing a Freudian Slip and adding some Velcro to it. The wheels are turning.
Thanks again everyone for your ideas, encouragement and support for my vertical organizer project.
