The Story

This was originally a vert simple mod: I simply wanted a backpack that carries things, to some extent.
The first step was to give the backpacks a simple feather enchantment. But if you have done any modding yourself, you know that the simplest idea can tirn into a massive project...
In this case, I imagined what an advenutrer's backpack would have: basic camping supplies, a few potions maybe. I cobbled up a script that would give you those itesm when you open (activate) your backpack and then put your gear back when you are ready to go.
Later on, I decided I should be able to add supplies to my backpack when I shop (that's the part where it got a little bit out of hand). Depending on the type of trader you are talking to, you get various supplies added to your pack. You get those supplies when you open your backpack.
It is quite a wonder (and sometimes slight frustration) to see a simple mod of your get more endorsements that you larger and more complex mods, but I guess it's just fine to have any endorsemnts at all;)
